Struct crayon::sched::latch::CountLatch

pub struct CountLatch { /* private fields */ }
Expand description

Counting latches are used to implement scopes. They track a counter. Unlike other latches, calling set() does not necessarily make the latch be considered set(); instead, it just decrements the counter. The latch is only “set” (in the sense thatis_set() returns true) once the counter reaches zero.

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. Read more
Convert Rc<Trait> (where Trait: Downcast) to Rc<Any>. Rc<Any> can then be further downcast into Rc<ConcreteType> where ConcreteType implements Trait. Read more
Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s. Read more
Convert &mut Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &mut Any’s vtable from &mut Trait’s. Read more
Convert Arc<Trait> (where Trait: Downcast) to Arc<Any>. Arc<Any> can then be further downcast into Arc<ConcreteType> where ConcreteType implements Trait. Read more

That is, this conversion is whatever the implementation of From<T> for U chooses to do.
