Expand description
Describes the OpenGL API and version that are being requested when a context is created.
Variants
Request the latest version of the “best” API of this platform.
On desktop, will try OpenGL.
Request a specific version of a specific API.
Example: GlRequest::Specific(Api::OpenGl, (3, 3))
.
If OpenGL is available, create an OpenGL Context
with the specified
opengl_version
. Else if OpenGL ES or WebGL is available, create a
context with the specified opengles_version
.

pub fn is_in_subset(&self) -> bool
pub fn is_in_subset(&self) -> bool
Checks if self
is actually part of its subset T
(and can be converted to it).
pub fn to_subset_unchecked(&self) -> SS
pub fn to_subset_unchecked(&self) -> SS
Use with care! Same as self.to_subset
but without any property checks. Always succeeds.
pub fn from_subset(element: &SS) -> SP
pub fn from_subset(element: &SS) -> SP
The inclusion map: converts self
to the equivalent element of its superset.
