![Nightly rust](https://img.shields.io/badge/rust-nightly-orange.svg)
## Installation
For end-users, librashader is available from the [Open Build Service](https://software.opensuse.org//download.html?project=home%3Achyyran%3Alibrashader&package=librashader) for a variety of Linux distributions and platforms. Windows users can grab the latest DLL from [GitHub Releases](https://github.com/SnowflakePowered/librashader/releases).

Windows and macOS users can grab the latest binaries from [GitHub Releases](https://github.com/SnowflakePowered/librashader/releases).
## Supported Render APIs
librashader supports OpenGL 3, OpenGL 4.6, Vulkan, Direct3D 11, and Direct3D 12. Metal and WebGPU
are not currently supported (but pull-requests are welcome). librashader does not support legacy render
APIs such as older versions of OpenGL, or legacy versions of Direct3D.
librashader supports all modern graphics runtimes, including wgpu, Vulkan, OpenGL 3.3+ and 4.6 (with DSA),
Direct3D 11, Direct3D 12, and Metal.
librashader does not support legacy render APIs such as older versions of OpenGL or Direct3D, except for experimental
support for Direct3D 9.

✔ = Render API is supported &mdash; ❌ Render API is not supported
✅ Full Support &mdash; 🆗 Secondary Support &mdash; ⚠️ Experimental Support
wgpu may not support all shaders due to restrictions from WGSL. Direct3D 9 support is experimental and does not fully
support features such as previous frame feedback or history, as well as being unable to support shaders that need Direct3D 10+
only features.

While librashader requires nightly Rust, the following MSRV policy is enforced for unstable library features.
