Represents a headless OpenGL context.
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§fn resize(&self, _size: PhysicalSize)
fn resize(&self, _size: PhysicalSize)
Resize the GL context. Read more

§fn into_any(self: Box<T, Global>) -> Box<dyn Any, Global>
fn into_any(self: Box<T, Global>) -> Box<dyn Any, Global>
Convert
Box<dyn Trait> (where Trait: Downcast) to Box<dyn Any>. Box<dyn Any> can
then be further downcast into Box<ConcreteType> where ConcreteType implements Trait.§fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>
fn into_any_rc(self: Rc<T>) -> Rc<dyn Any>
Convert
Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be
further downcast into Rc<ConcreteType> where ConcreteType implements Trait.§fn as_any(&self) -> &(dyn Any + 'static)
fn as_any(&self) -> &(dyn Any + 'static)
Convert
&Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &Any’s vtable from &Trait’s.§fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)
Convert
&mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot
generate &mut Any’s vtable from &mut Trait’s.
