Trait Implementations§
Source§impl GlContext for HeadlessContext
impl GlContext for HeadlessContext
Source§unsafe fn make_current(&self) -> Result<(), ContextError>
unsafe fn make_current(&self) -> Result<(), ContextError>
Creates a new OpenGL context Sets the context as the current context.
Source§fn is_current(&self) -> bool
fn is_current(&self) -> bool
Returns true if this context is the current one in this thread.
Source§fn get_proc_address(&self, addr: &str) -> *const ()
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§fn get_api(&self) -> Api
fn get_api(&self) -> Api
Returns the API that is currently provided by this window.
See Window::get_api for more infos.
Source§fn swap_buffers(&self) -> Result<(), ContextError>
fn swap_buffers(&self) -> Result<(), ContextError>
Swaps the buffers in case of double or triple buffering. Read more
Source§fn get_pixel_format(&self) -> PixelFormat
fn get_pixel_format(&self) -> PixelFormat
Returns the pixel format of the main framebuffer of the context.
Source§impl GlContextExt for HeadlessContext
impl GlContextExt for HeadlessContext
Source§unsafe fn raw_handle(&self) -> <HeadlessContext as GlContextExt>::Handle
unsafe fn raw_handle(&self) -> <HeadlessContext as GlContextExt>::Handle
Returns the raw context handle.
