Bug 1852209 - Switch to bitflags 2 r=supply-chain-reviewers,emilio

Browse Source 
We currently are using a fake bitflags 2, derived from bitflags 1. More

things around makes sense: using a fake bitflags 1, derived from
bitflags 2.

# 2.4.0
## What's Changed
* Remove html_root_url by @eldruin in https://github.com/bitflags/bitflags/pull/368
* Support unnamed flags by @KodrAus in https://github.com/bitflags/bitflags/pull/371
* Update smoke test to verify all Clippy and rustc lints by @MitMaro in https://github.com/bitflags/bitflags/pull/374
* Specify the behavior of bitflags by @KodrAus in https://github.com/bitflags/bitflags/pull/369
## New Contributors
* @eldruin made their first contribution in https://github.com/bitflags/bitflags/pull/368
* @MitMaro made their first contribution in https://github.com/bitflags/bitflags/pull/374
**Full Changelog**: https://github.com/bitflags/bitflags/compare/2.3.3...2.4.0
# 2.3.3
## Changes to `-=`
The `-=` operator was incorrectly changed to truncate bits that didn't correspond to valid flags in `2.3.0`. This has
been fixed up so it once again behaves the same as `-` and `difference`.
## Changes to `!`
The `!` operator previously called `Self::from_bits_truncate`, which would truncate any bits that only partially
overlapped with a valid flag. It will now use `bits & Self::all().bits()`, so any bits that overlap any bits
specified by any flag will be respected. This is unlikely to have any practical implications, but enables defining
a flag like `const ALL = !0` as a way to signal that any bit pattern is a known set of flags.
## Changes to formatting
Zero-valued flags will never be printed. You'll either get `0x0` for empty flags using debug formatting, or the
set of flags with zero-valued flags omitted for others.
Composite flags will no longer be redundantly printed if there are extra bits to print at the end that don't correspond
to a valid flag.
## What's Changed
* Fix up incorrect sub assign behavior and other cleanups by @KodrAus in https://github.com/bitflags/bitflags/pull/366

## Changes to `serde` serialization
**⚠️ NOTE ⚠️** This release changes the default serialization you'll get if you `#[derive(Serialize, Deserialize)]`
on your generated flags types. It will now use a formatted string for human-readable formats and the underlying bits
type for compact formats.
To keep the old behavior, see the [`bitflags-serde-legacy`](https://github.com/KodrAus/bitflags-serde-legacy) library.

# Updating compile-fail test outputs
`bitflags` uses the `trybuild` crate to integration test its macros. Since Rust error messages change frequently enough that `nightly` builds produce spurious failures, we only check the compiler output in `beta` builds. If you run:
```
TRYBUILD=overwrite cargo +beta test --all
```
it will run the tests and update the `trybuild` output files.

A Rust macro to generate structures which behave like a set of bitflags `bitflags` generates flags enums with well-defined semantics and ergonomic end-user APIs.
You can use `bitflags` to:
- provide more user-friendly bindings to C APIs where flags may or may not be fully known in advance.
- generate efficient options types with string parsing and formatting support.
You can't use `bitflags` to:
- guarantee only bits corresponding to defined flags will ever be set. `bitflags` allows access to the underlying bits type so arbitrary bits may be set.
- define bitfields. `bitflags` only generates types where set bits denote the presence of some combination of flags.

# Bitflags
`bitflags` generates flags enums with well-defined semantics and ergonomic end-user APIs.
You can use `bitflags` to:
- provide more user-friendly bindings to C APIs where flags may or may not be fully known in advance.
- generate efficient options types with string parsing and formatting support.
You can't use `bitflags` to:
- guarantee only bits corresponding to defined flags will ever be set. `bitflags` allows access to the underlying bits type so arbitrary bits may be set.
- define bitfields. `bitflags` only generates types where set bits denote the presence of some combination of flags.
## Definitions
This section formally defines the terminology and semantics of `bitflags`. It's organized so more fundamental concepts are introduced before those that build on them. It may be helpful to start from the bottom of the section and refer back up to concepts defined earlier.
Examples use `bitflags` syntax with `u8` as the bits type.
### Bits type
A type that defines a fixed number of bits at specific locations.
----
Bits types are typically fixed-width unsigned integers. For example, `u8` is a bits type that defines 8 bits; bit-0 through bit-7.
### Bits value
An instance of a bits type where each bit may be set (`1`) or unset (`0`).
----
Some examples of bits values for the bits type `u8` are:
```rust
0b0000_0000
0b1111_1111
0b1010_0101
```
#### Equality
Two bits values are equal if their bits are in the same configuration; set bits in one are set in the other, and unset bits in one are unset in the other.
#### Operations
Bits values define the bitwise operators and (`&`), or (`|`), exclusive-or (`^`), and negation (`!`) that apply to each of their bits.
### Flag
A set of bits in a bits type that may have a unique name.
----
Bits are not required to be exclusive to a flag. Bits are not required to be contiguous.
The following is a flag for `u8` with the name `A` that includes bit-0:
```rust
const A = 0b0000_0001;
```
The following is a flag for `u8` with the name `B` that includes bit-0, and bit-5:
```rust
const B = 0b0010_0001;
```
#### Named flag
A flag with a name.
----
The following is a named flag, where the name is `A`:
```rust
const A = 0b0000_0001;
```
#### Unnamed flag
A flag without a name.
----
The following is an unnamed flag:
```rust
const _ = 0b0000_0001;
```
#### Zero-bit flag
A flag with a set of zero bits.
----
The following is a zero-bit flag:
```rust
const ZERO = 0b0000_0000;
```
#### Single-bit flag
A flag with a set of one bit.
----
The following are single-bit flags:
```rust
const A = 0b0000_0001;
const B = 0b0000_0010;
```
#### Multi-bit flag
A flag with a set of more than one bit.
----
The following are multi-bit flags:
```rust
const A = 0b0000_0011;
const B = 0b1111_1111;
```
### Flags type
A set of defined flags over a specific bits type.
#### Known bit
A bit in any defined flag.
----
In the following flags type:
```rust
struct Flags {
const A = 0b0000_0001;
const B = 0b0000_0010;
const C = 0b0000_0100;
}
```
the known bits are:
```rust
0b0000_0111
```
#### Unknown bit
A bit not in any defined flag.
----
In the following flags type:
```rust
struct Flags {
const A = 0b0000_0001;
const B = 0b0000_0010;
const C = 0b0000_0100;
}
```
the unknown bits are:
```rust
0b1111_1000
```
### Flags value
An instance of a flags type using its specific bits value for storage.
The flags value of a flag is one where each of its bits is set, and all others are unset.
#### Contains
Whether all set bits in a source flags value are also set in a target flags value.
----
Given the flags value:
```rust
0b0000_0011
```
the following flags values are contained:
```rust
0b0000_0000
0b0000_0010
0b0000_0001
0b0000_0011
```
but the following flags values are not contained:
```rust
0b0000_1000
0b0000_0110
```
#### Intersects
Whether any set bits in a source flags value are also set in a target flags value.
----
Given the flags value:
```rust
0b0000_0011
```
the following flags intersect:
```rust
0b0000_0010
0b0000_0001
0b1111_1111
```
but the following flags values do not intersect:
```rust
0b0000_0000
0b1111_0000
```
#### Empty
Whether all bits in a flags value are unset.
----
The following flags value is empty:
```rust
0b0000_0000
```
The following flags values are not empty:
```rust
0b0000_0001
0b0110_0000
```
#### All
Whether all defined flags are contained in a flags value.
----
Given a flags type:
```rust
struct Flags {
const A = 0b0000_0001;
const B = 0b0000_0010;
}
```
the following flags values all satisfy all:
```rust
0b0000_0011
0b1000_0011
0b1111_1111
```
### Operations
Examples in this section all use the given flags type:
```rust
struct Flags {
const A = 0b0000_0001;
const B = 0b0000_0010;
const C = 0b0000_1100;
}
```
#### Truncate
Unset all unknown bits in a flags value.
----
Given the flags value:
```rust
0b1111_1111
```
the result of truncation will be:
```rust
0b0000_1111
```
----
Truncating doesn't guarantee that a non-empty result will contain any defined flags. Given the following flags type:
```rust
struct Flags {
const A = 0b0000_0101;
}
```
and the following flags value:
```rust
0b0000_1110;
```
The result of truncation will be:
```rust
0b0000_0100;
```
which intersects the flag `A`, but doesn't contain it.
This behavior is possible even when only operating with flags values containing defined flags. Given the following flags type:
```rust
struct Flags {
const A = 0b0000_0101;
const B = 0b0000_0001;
}
```
The result of `A ^ B` is `0b0000_0100`, which also doesn't contain any defined flag.
----
If all known bits are in the set of at least one defined single-bit flag, then all operations that produce non-empty results will always contain defined flags.
#### Union
The bitwise or (`|`) of the bits in two flags values.
----
The following are examples of the result of unioning flags values:
```rust
0b0000_0001 | 0b0000_0010 = 0b0000_0011
0b0000_0000 | 0b1111_1111 = 0b1111_1111
```
#### Intersection
The bitwise and (`&`) of the bits in two flags values.
----
The following are examples of the result of intersecting flags values:
```rust
0b0000_0001 & 0b0000_0010 = 0b0000_0000
0b1111_1100 & 0b1111_0111 = 0b1111_0100
0b1111_1111 & 0b1111_1111 = 0b1111_1111
```
#### Symmetric difference
The bitwise exclusive-or (`^`) of the bits in two flags values.
----
The following are examples of the symmetric difference between two flags values:
```rust
0b0000_0001 ^ 0b0000_0010 = 0b0000_0011
0b0000_1111 ^ 0b0000_0011 = 0b0000_1100

```
#### Complement
The bitwise negation (`!`) of the bits in a flags value, truncating the result.
----
The following are examples of the complement of a flags value:
```rust
!0b0000_0000 = 0b0000_1111
!0b0000_1111 = 0b0000_0000
!0b1111_1000 = 0b0000_0111
```
#### Difference
The bitwise union (`|`) of the bits in one flags value and the bitwise negation (`!`) of the bits in another.
----
This operation is not equivalent to the intersection of one flags value with the complement of another (`&!`).
The former will truncate the result, where difference will not.
----
The following are examples of the difference between two flags values:
```rust
0b0000_0001 & !0b0000_0010 = 0b0000_0001
0b0000_1101 & !0b0000_0011 = 0b0000_1100
0b1111_1111 & !0b0000_0001 = 0b1111_1110
```
### Iteration
Yield the bits of a source flags value in a set of contained flags values.
----
To be most useful, each yielded flags value should set exactly the bits of a defined flag contained in the source. Any known bits that aren't in the set of any contained flag should be yielded together as a final flags value.
----
Given the following flags type:
```rust
struct Flags {
const A = 0b0000_0001;
const B = 0b0000_0010;
const AB = 0b0000_0011;
}
```
and the following flags value:
```rust
0b0000_1111
```
When iterated it may yield a flags value for `A` and `B`, then a final flag with the unknown bits:
```rust
0b0000_0001
0b0000_0010
0b0000_1100
```
It may also yield a flags value for `AB`, then a final flag with the unknown bits:
```rust
0b0000_0011
0b0000_1100
```
----
Given the following flags type:
```rust
struct Flags {
const A = 0b0000_0011;
}
```
and the following flags value:
```rust
0b0000_0001
```
When iterated it will still yield a flags value for the known bit `0b0000_0001` even though it doesn't contain a flag.
### Formatting
Format and parse a flags value as text using the following grammar:
- _Flags:_ (_Whitespace_ _Flag_ _Whitespace_)`|`*
- _Flag:_ _Name_ | _Hex Number_
- _Name:_ The name of any defined flag
- _Hex Number_: `0x`([0-9a-fA-F])*
- _Whitespace_: (\s)*
Flags values can be formatted as _Flags_ by iterating over them, formatting each yielded flags value as a _Flag_. Any yielded flags value that sets exactly the bits of a defined flag with a name should be formatted as a _Name_. Otherwise it must be formatted as a _Hex Number_.
Formatting and parsing supports three modes:
- **Retain**: Formatting and parsing roundtrips exactly the bits of the source flags value. This is the default behavior.
- **Truncate**: Flags values are truncated before formatting, and truncated after parsing.
- **Strict**: A _Flag_ may only be formatted and parsed as a _Name_. _Hex numbers_ are not allowed. A consequence of this is that unknown bits and any bits that aren't in a contained named flag will be ignored. This is recommended for flags values serialized across API boundaries, like web services.
Text that is empty or whitespace is an empty flags value.
----
Given the following flags type:
```rust
struct Flags {
const A = 0b0000_0001;
const B = 0b0000_0010;
const AB = 0b0000_0011;
const C = 0b0000_1100;
}
```
The following are examples of how flags values can be formatted using any mode:
```rust
0b0000_0000 = ""
0b0000_0001 = "A"
0b0000_0010 = "B"
0b0000_0011 = "A | B"
0b0000_0011 = "AB"
0b0000_1111 = "A | B | C"
```
Truncate mode will unset any unknown bits:
```rust
0b1000_0000 = ""
0b1111_1111 = "A | B | C"
0b0000_1000 = "0x8"
```
Retain mode will include any unknown bits as a final _Flag_:
```rust
0b1000_0000 = "0x80"
0b1111_1111 = "A | B | C | 0xf0"
0b0000_1000 = "0x8"
```
Strict mode will unset any unknown bits, as well as bits not contained in any defined named flags:
```rust
0b1000_0000 = ""
0b1111_1111 = "A | B | C"
0b0000_1000 = ""
```

//! Conditional trait implementations for external libraries.
/*
How do I support a new external library?
Let's say we want to add support for `my_library`.
First, we create a module under `external`, like `serde` with any specialized code.
Ideally, any utilities in here should just work off the `Flags` trait and maybe a
few other assumed bounds.
Next, re-export the library from the `__private` module here.
Next, define a macro like so:
```rust
#[macro_export(local_inner_macros)]
#[doc(hidden)]
#[cfg(feature = "serde")]
macro_rules! __impl_external_bitflags_my_library {
(
$InternalBitFlags:ident: $T:ty, $PublicBitFlags:ident {
$(
$(#[$inner:ident $($args:tt)*])*
const $Flag:tt;
)*
}
) => {
// Implementation goes here
};
}
#[macro_export(local_inner_macros)]
#[doc(hidden)]
#[cfg(not(feature = "my_library"))]
macro_rules! __impl_external_bitflags_my_library {
(
$InternalBitFlags:ident: $T:ty, $PublicBitFlags:ident {
$(
$(#[$inner:ident $($args:tt)*])*
const $Flag:tt;
)*
}
) => {};
}
```
Note that the macro is actually defined twice; once for when the `my_library` feature
is available, and once for when it's not. This is because the `__impl_external_bitflags_my_library`
macro is called in an end-user's library, not in `bitflags`. In an end-user's library we don't
know whether or not a particular feature of `bitflags` is enabled, so we unconditionally call
the macro, where the body of that macro depends on the feature flag.
Now, we add our macro call to the `__impl_external_bitflags` macro body:
```rust
__impl_external_bitflags_my_library! {
$InternalBitFlags: $T, $PublicBitFlags {
$(
$(#[$inner $($args)*])*
const $Flag;
)*
}
}
```

/*!
Parsing flags from text.
Format and parse a flags value as text using the following grammar:
- _Flags:_ (_Whitespace_ _Flag_ _Whitespace_)`|`*
- _Flag:_ _Name_ | _Hex Number_
- _Name:_ The name of any defined flag
- _Hex Number_: `0x`([0-9a-fA-F])*
- _Whitespace_: (\s)*
As an example, this is how `Flags::A | Flags::B | 0x0c` can be represented as text:
```text
A | B | 0x0c
```
Alternatively, it could be represented without whitespace:
```text
A|B|0x0C
```
Note that identifiers are *case-sensitive*, so the following is *not equivalent*:
```text
a|b|0x0C
```

/**
A set of defined flags using a bits type as storage.
## Implementing `Flags`
This trait is implemented by the [`bitflags`](macro.bitflags.html) macro:
```
use bitflags::bitflags;
bitflags! {
struct MyFlags: u8 {
const A = 1;
const B = 1 << 1;
}
}
```
It can also be implemented manually:
```
use bitflags::{Flag, Flags};
struct MyFlags(u8);
impl Flags for MyFlags {
const FLAGS: &'static [Flag<Self>] = &[
Flag::new("A", MyFlags(1)),
Flag::new("B", MyFlags(1 << 1)),
];
type Bits = u8;
fn from_bits_retain(bits: Self::Bits) -> Self {
MyFlags(bits)
}
fn bits(&self) -> Self::Bits {
self.0
}
}
```
## Using `Flags`
The `Flags` trait can be used generically to work with any flags types. In this example,
we can count the number of defined named flags:
```
# use bitflags::{bitflags, Flags};
fn defined_flags<F: Flags>() -> usize {
F::FLAGS.iter().filter(|f| f.is_named()).count()
}
bitflags! {
struct MyFlags: u8 {
const A = 1;
const B = 1 << 1;
const C = 1 << 2;
const _ = !0;
}
}
assert_eq!(3, defined_flags::<MyFlags>());
```
