[−]

Trait for types that can be used as a backend for a glium context.

This trait is unsafe, as you can get undefined behaviors or crashes if you don't implement the methods correctly.

Required methods

fn swap_buffers(&self) -> Result<(), SwapBuffersError>[−]

Swaps buffers at the end of a frame.

unsafe fn get_proc_address(&self, symbol: &str) -> *const c_void[−]

Returns the address of an OpenGL function.

Supposes that the context has been made current before this function is called.

fn get_framebuffer_dimensions(&self) -> (u32, u32)[−]

Returns the dimensions of the window, or screen, etc.

fn is_current(&self) -> bool[−]

Returns true if the OpenGL context is the current one in the thread.

unsafe fn make_current(&self)[−]

Makes the OpenGL context the current context in the current thread.
