Create UTF-8 version of `OsStr`/`OsString` Implement a UTF-8 version of `OsStr`/`OsString`, in addition to the existing bytes and WTF-8 platform-dependent encodings. This is applicable for several platforms, but I've currently only implemented it for Motor OS: - WASI uses Unicode paths, but currently reexports the Unix bytes-assuming `OsStrExt`/`OsStringExt` traits. - [wasi:filesystem](https://wa.dev/wasi:filesystem) APIs: > Paths are passed as interface-type `strings`, meaning they must consist of a sequence of Unicode Scalar Values (USVs). Some filesystems may contain paths which are not accessible by this API. - In [wasi-filesystem#17](https://github.com/WebAssembly/wasi-filesystem/issues/17#issuecomment-1430639353), it was decided that applications can use any Unicode transformation format, so we're free to use UTF-8 (and probably already do). This was chosen over specifically UTF-8 or an ad hoc encoding which preserves paths not representable in UTF-8. > The current API uses strings for filesystem paths, which contains sequences of Unicode scalar values (USVs), which applications can work with using strings encoded in UTF-8, UTF-16, or other Unicode encodings. > > This does mean that the API is unable to open files which do not have well-formed Unicode encodings, which may want separate APIs for handling such paths or may want something like the arf-strings proposal, but if we need that we should file a new issue for it. - As of Redox OS [0.7.0](https://www.redox-os.org/news/release-0.7.0/), "All paths are now required to be UTF-8, and the kernel enforces this". This appears to have been implemented in commit [d331f72f]( |

This is the main source code repository for Rust. It contains the compiler, standard library, and documentation.
Why Rust?
-
Performance: Fast and memory-efficient, suitable for critical services, embedded devices, and easily integrated with other languages.
-
Reliability: Our rich type system and ownership model ensure memory and thread safety, reducing bugs at compile-time.
-
Productivity: Comprehensive documentation, a compiler committed to providing great diagnostics, and advanced tooling including package manager and build tool (Cargo), auto-formatter (rustfmt), linter (Clippy) and editor support (rust-analyzer).
