Represents a headless OpenGL context.

Methods

unsafe fn make_current(&self) -> Result<(), ContextError>[−]

Creates a new OpenGL context Sets the context as the current context.

fn is_current(&self) -> bool[−]

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

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

Returns the address of an OpenGL function.

Contrary to wglGetProcAddress, all available OpenGL functions return an address.

fn get_api(&self) -> Api[−]

Returns the API that is currently provided by this window.

See Window::get_api for more infos.

fn set_window_resize_callback(&mut self, _: Option<fn(u32, u32)>)
