Struct rafx_base::atomic_once_cell::AtomicOnceCell[−][src]

pub struct AtomicOnceCell<T> { /* fields omitted */ }
Expand description

A thread-safe container that does not require default initialization. The cell may be initialized with set and then retrieved as a reference with get. Calling set is thread-safe. The cell will panic if the set function is called more than once. The cell will only drop initialized elements.

Guarantees

  • The allocated memory will not be default initialized.
  • Elements initialized by set are immutable.
  • The synchronization is lock-free.

impl<T> Downcast for T where
    T: Any, [src]

pub fn into_any(self: Box<T, Global>) -> Box<dyn Any + 'static, Global>[src]

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

pub fn into_any_rc(self: Rc<T>) -> Rc<dyn Any + 'static>[src]

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

pub fn as_any(&self) -> &(dyn Any + 'static)[src]

Convert &Trait (where Trait: Downcast) to &Any. This is needed since Rust cannot generate &Any’s vtable from &Trait’s. Read more

pub fn as_any_mut(&mut self) -> &mut (dyn Any + 'static)[src]

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
