bitflags
========
A Rust macro to generate structures which behave like a set of bitflags
[![Build Status](https://travis-ci.org/rust-lang-nursery/bitflags.svg?branch=master)](https://travis-ci.org/rust-lang-nursery/bitflags)
[Documentation](https://doc.rust-lang.org/bitflags)
## Usage
Add this to your `Cargo.toml`:
```toml
[dependencies]
bitflags = "0.7"
```
and this to your crate root:
```rust
#[macro_use]
extern crate bitflags;
```
## 128-bit integer bitflags (nightly only)
Add this to your `Cargo.toml`:
```toml
[dependencies.bitflags]
version = "0.7"
features = ["i128"]
```
and this to your crate root:
```rust
#![feature(i128_type)]
#[macro_use]
extern crate bitflags;
```

/// The `bitflags!` macro generates a `struct` that holds a set of C-style
/// bitmask flags. It is useful for creating typesafe wrappers for C APIs.
///
/// The flags should only be defined for integer types, otherwise unexpected
/// type errors may occur at compile time.
///
/// # Example
///
/// ```{.rust}
/// #[macro_use]
/// extern crate bitflags;
///
/// bitflags! {
/// flags Flags: u32 {
/// const FLAG_A = 0b00000001,
/// const FLAG_B = 0b00000010,
/// const FLAG_C = 0b00000100,
/// const FLAG_ABC = FLAG_A.bits
/// | FLAG_B.bits
/// | FLAG_C.bits,
/// }
/// }
///
/// fn main() {
/// let e1 = FLAG_A | FLAG_C;
/// let e2 = FLAG_B | FLAG_C;
/// assert_eq!((e1 | e2), FLAG_ABC); // union
/// assert_eq!((e1 & e2), FLAG_C); // intersection
/// assert_eq!((e1 - e2), FLAG_A); // set difference
/// assert_eq!(!e2, FLAG_A); // set complement
/// }
/// ```
///
/// The generated `struct`s can also be extended with type and trait
/// implementations:
///
/// ```{.rust}
/// #[macro_use]
/// extern crate bitflags;
///
/// use std::fmt;
///
/// bitflags! {
/// flags Flags: u32 {
/// const FLAG_A = 0b00000001,
/// const FLAG_B = 0b00000010,
/// }
/// }
///
/// impl Flags {
/// pub fn clear(&mut self) {
/// self.bits = 0; // The `bits` field can be accessed from within the
/// // same module where the `bitflags!` macro was invoked.
/// }
/// }
///
/// impl fmt::Display for Flags {
/// fn fmt(&self, f: &mut fmt::Formatter) -> fmt::Result {
/// write!(f, "hi!")
/// }
/// }
///
/// fn main() {
/// let mut flags = FLAG_A | FLAG_B;
/// flags.clear();
/// assert!(flags.is_empty());
/// assert_eq!(format!("{}", flags), "hi!");
/// assert_eq!(format!("{:?}", FLAG_A | FLAG_B), "FLAG_A | FLAG_B");
/// assert_eq!(format!("{:?}", FLAG_B), "FLAG_B");
/// }
/// ```
///
/// # Visibility
///
/// The generated struct and its associated flag constants are not exported
/// out of the current module by default. A definition can be exported out of
/// the current module by adding `pub` before `flags`:
///
/// ```{.rust},ignore
/// #[macro_use]
/// extern crate bitflags;
///
/// mod example {
/// bitflags! {
/// pub flags Flags1: u32 {
/// const FLAG_A = 0b00000001,
/// }
/// }
/// bitflags! {
/// flags Flags2: u32 {
/// const FLAG_B = 0b00000010,
/// }
/// }
/// }
///
/// fn main() {
/// let flag1 = example::FLAG_A;
/// let flag2 = example::FLAG_B; // error: const `FLAG_B` is private
/// }
/// ```
///
/// # Attributes
///
/// Attributes can be attached to the generated `struct` by placing them
/// before the `flags` keyword.
///
/// # Trait implementations
///
/// The `Copy`, `Clone`, `PartialEq`, `Eq`, `PartialOrd`, `Ord` and `Hash`
/// traits automatically derived for the `struct` using the `derive` attribute.
/// Additional traits can be derived by providing an explicit `derive`
/// attribute on `flags`.
///
/// The `Extend` and `FromIterator` traits are implemented for the `struct`,
/// too: `Extend` adds the union of the instances of the `struct` iterated over,
/// while `FromIterator` calculates the union.
///
/// The `Debug` trait is also implemented by displaying the bits value of the
/// internal struct.
///
/// ## Operators
///
/// The following operator traits are implemented for the generated `struct`:
///
/// - `BitOr` and `BitOrAssign`: union
/// - `BitAnd` and `BitAndAssign`: intersection
/// - `BitXor` and `BitXorAssign`: toggle
/// - `Sub` and `SubAssign`: set difference
/// - `Not`: set complement
///
/// As long as the assignment operators are unstable rust feature they are only
/// available with the crate feature `assignment_ops` enabled.
///
/// # Methods
///
/// The following methods are defined for the generated `struct`:
///
/// - `empty`: an empty set of flags
/// - `all`: the set of all flags
/// - `bits`: the raw value of the flags currently stored
/// - `from_bits`: convert from underlying bit representation, unless that
/// representation contains bits that do not correspond to a flag
/// - `from_bits_truncate`: convert from underlying bit representation, dropping
/// any bits that do not correspond to flags
/// - `is_empty`: `true` if no flags are currently stored
/// - `is_all`: `true` if all flags are currently set
/// - `intersects`: `true` if there are flags common to both `self` and `other`
/// - `contains`: `true` all of the flags in `other` are contained within `self`
/// - `insert`: inserts the specified flags in-place
/// - `remove`: removes the specified flags in-place
/// - `toggle`: the specified flags will be inserted if not present, and removed
/// if they are.
