Struct Context

pub struct Context { /* private fields */ }

An OpenGL context.

A context encapsulates the OpenGL specific setup and state on a window. Hence, conceptually a context is associated with a window, but that does not have to be a winit created one (and can also include one not managed at the Rust level at all).

Implementations

impl Context

pub fn new( display: &Display, config: &Config, window: &WinitWindow, ) -> Result<Self>

Create a new OpenGL context on the given window.

pub fn from_xlib_data( display_handle: XlibDisplayHandle, window_handle: XlibWindowHandle, phys_w: NonZeroU32, phys_h: NonZeroU32, ) -> Result<Self>

Create a new OpenGL context given some xlib display & window state.

pub fn on_resize(&mut self, phys_w: NonZeroU32, phys_h: NonZeroU32)

Inform the surface that the window has been resized.

pub fn swap_buffers(&mut self)

Swap the rendering buffers to activate the one that any rendering operations occurred on.

Trait Implementations

impl Debug for Context

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
