# edgefirst-gl

Minimal OpenGL ES bindings used by the EdgeFirst HAL.

This crate is a **trimmed, maintained fork** of [`gls`](https://github.com/vaxpl/gls-rs)
0.1.6 by Varphone Wong, which became unmaintained. Only the surface the HAL
actually uses is retained:

- the raw `gl` bindings (generated at build time by `gl_generator`, GLES 3.2 +
  the `GL_OES_EGL_image` / `GL_OES_EGL_image_external` / `GL_EXT_YUV_target`
  extensions),
- a small set of safe wrappers (`apis`),
- the `Error` type.

The upstream higher-level helpers (textures, framebuffers, shaders, buffers,
viewport math) and their `nalgebra` / `serde` / `libc` / `winapi` dependencies
have been removed, so this crate has **no runtime dependencies**.

The library is imported as `edgefirst_gl`:

```rust
use edgefirst_gl as gls; // optional alias
```
