[−]Struct processing::backend::glutin::glutin::HeadlessContext
Represents a headless OpenGL context.
Trait Implementations
impl GlContext for HeadlessContext
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 swap_buffers(&self) -> Result<(), ContextError>
fn get_pixel_format(&self) -> PixelFormat
fn resize(&self, _width: u32, _height: u32)
impl GlContextExt for HeadlessContext
type Handle = *mut c_void
Raw context handle.
unsafe fn raw_handle(&self) -> <HeadlessContext as GlContextExt>::Handle
