Struct rg3d::Context [−][src]
pub struct Context<T> where
T: ContextCurrentState, { /* fields omitted */ }
Expand description
Represents an OpenGL Context
.
A Context
is normally associated with a single Window, however
Context
s can be shared between multiple windows or be headless.
If a Context
is backed by a window, it will be wrapped by either
RawContext<T>
or WindowedContext<T>
.
Example
let cb = glutin::ContextBuilder::new()
.with_vsync(true)
.with_multisampling(8)
.with_shared_lists(some_context.context());

The inverse inclusion map: attempts to construct self
from the equivalent element of its
superset. Read more
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.
