Module smithay::backend::egl

Common traits and types for egl rendering

Large parts of this module are taken from glutin src/api/egl

Wayland specific EGL functionality - EGL based WlBuffers.

The types of this module can be used to initialize hardware acceleration rendering based on EGL for clients as it may enabled usage of EGLImage based WlBuffers.

To use it bind any backend implementing the EGLGraphicsBackend trait, that shall do the rendering (so pick a fast one), to the wayland_server::Display of your compositor. Note only one backend may be bound to any Display at any time.

You may then use the resulting EGLDisplay to receive EGLImages of an EGL-based WlBuffer for rendering.
