Struct glutin::HeadlessContext

source ·
pub struct HeadlessContext { /* private fields */ }
Expand description

Represents a headless OpenGL context.

Implementations§

source§

impl HeadlessContext

source

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

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

source

pub fn is_current(&self) -> bool

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

source

pub 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.

source

pub fn get_api(&self) -> Api

Returns the API that is currently provided by this window.

See Window::get_api for more infos.

source

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