Enum futures::Async
[−]
[src]
pub enum Async<T> {
Ready(T),
NotReady,
}Return type of future, indicating whether a value is ready or not.
Variants
Ready(T)Represents that a value is immediately ready.
NotReadyRepresents that a value is not ready yet, but may be so later.
Methods
impl<T> Async<T>[src]
pub fn map<F, U>(self, f: F) -> Async<U> where
F: FnOnce(T) -> U, [src]
F: FnOnce(T) -> U,
Change the success value of this Async with the closure provided
pub fn is_ready(&self) -> bool[src]
Returns whether this is Async::Ready
pub fn is_not_ready(&self) -> bool[src]
Returns whether this is Async::NotReady
