Merge pull request #984 from benesch/lossy 
Add String::lossy constructors to C++ API
 2021-12-31 13:19:37 -08:00

Add String::lossy constructors to C++ API 
This constructor maps to `String::from_utf8_lossy` or
`String::from_utf16_lossy`. It's useful in situations where producing a
slightly garbled string on invalid Unicode data is preferable to
crashing the process, e.g. when passing error messages from C++ to Rust.

Add Vec<T>::truncate to C++ API 
Based on the model of #951, which added `Vec<T>::clear`. The `truncate`
method is the more general form of clear.

(If we wanted to, we could delete the binding for `clear` and implement
`clear` as a call to `truncate(0)` on the C++ side, but seemed worth
leaving in in case the Rust `clear` implementation one day gets
smarter.)

Move swap member functions below less-niche functions 
The swap member functions are going to be infrequently used (relative to
things like operator==, Box's operator->) so let's present it lower down
in the API.

f45f899cd0 Add swap members + ADL functions 
Addresses #58.

Adds `swap` members to each of `Slice`, `Str`, `Vec`, `Box`, and `String`. Also adds private friend functions so that Argument Dependent Lookup may function via the `using std::swap;` idiom.

Rename Box value_type to element_type 
This matches the member type naming on unique_ptr.
https://en.cppreference.com/w/cpp/memory/unique_ptr#Member_types
It appears value_type is for a member type of a container or iterator
while element_type is for the target of a smart pointer.
