Required Associated Types

type Handle

Required Methods

fn get_proc_address(_: &str) -> *const ()

fn current() -> Option<Self>

fn current_handle() -> Option<Self::Handle>

fn create_shared(
    with: Option<&Self::Handle>,
    api_type: &GlType,
    api_version: GLVersion
) -> Result<Self, &'static str>

fn handle(&self) -> Self::Handle

fn is_current(&self) -> bool

fn make_current(&self) -> Result<(), &'static str>

fn unbind(&self) -> Result<(), &'static str>

Provided Methods

fn create_shared_with_dispatcher(
    with: Option<&Self::Handle>,
    api_type: &GlType,
    api_version: GLVersion,
    _dispatcher: Option<Box<dyn GLContextDispatcher>>
) -> Result<Self, &'static str>

fn create_headless(
    api_type: &GlType,
    api_version: GLVersion
) -> Result<Self, &'static str>

fn is_osmesa(&self) -> bool

Just a somewhat dirty hack to special-case the handling of context unbinding on old OSMesa versions.
