Struct glutin::RawContext

pub struct RawContext { /* private fields */ }

Represents a raw OpenGL context.

Implementations

impl RawContext

pub fn swap_buffers(&self) -> Result<(), ContextError>

Swaps the buffers in case of double or triple buffering.

You should call this function every time you have finished rendering, or the image may not be displayed on the screen.

Warning: if you enabled vsync, this function will block until the next time the screen is refreshed. However drivers can choose to override your vsync settings, which means that you can’t know in advance whether swap_buffers will block or not.

pub fn get_pixel_format(&self) -> PixelFormat

Returns the pixel format of the main framebuffer of the context.

pub fn resize(&self, size: PhysicalSize)

Resize the context.

Some platforms (macOS, Wayland) require being manually updated when their window or surface is resized.

The easiest way of doing this is to take every Resized window event that is received with a LogicalSize and convert it to a PhysicalSize and pass it into this function.

Trait Implementations

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.

fn get_api(&self) -> Api

Returns the OpenGL API being used.

impl Deref for RawContext

type Target = Context

The resulting type after dereferencing.

fn deref(&self) -> &Self::Target

Dereferences the value.
