# widestring
[](https://crates.io/crates/widestring/) [](https://docs.rs/widestring/)  [](https://github.com/starkat99/widestring-rs/actions/workflows/rust.yml)
A wide string Rust library for converting to and from wide strings, such as
those often used in Windows API or other FFI libaries. Both `u16` and `u32` string types are
provided, including support for UTF-16 and UTF-32, malformed encoding, C-style strings, etc.
Macros for converting string literals to UTF-16 and UTF-32 strings at compile time are also
included.

### Optional Features
- **`alloc`** - Enabled by default. Enable use of the [`alloc`](https://doc.rust-lang.org/alloc/)
crate when not using the `std` library.
This enables the owned string types and aliases.
- **`std`** - Enabled by default. Enable features that depend on the Rust `std` library, including
everything in the `alloc` feature.
