/* private fields */
}Expand description
Shared draw state
A single SharedState instance is shared by all windows and draw contexts.
This struct is built over a [DrawSharedImpl] object provided by the shell,
which may be accessed directly for a lower-level API (though most methods
are available through SharedState directly).
Note: all functionality is implemented through the DrawShared trait to
allow usage where the DS type parameter is unknown. Some functionality is
also implemented directly to avoid the need for downcasting.

§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, Global>) -> Rc<dyn Any, Global>
fn into_any_rc(self: Rc<T, Global>) -> Rc<dyn Any, Global>
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.
