[][src]Enum futures::future::Either

pub enum Either<A, B> {
    Left(A),
    Right(B),
}

Combines two different futures, streams, or sinks having the same associated types into a single type.

Variants

Left(A)

First branch of the type

Right(B)

Second branch of the type

Methods

impl<A, B, T> Either<(T, A), (T, B)>[src]

pub fn factor_first(self) -> (T, Either<A, B>)[src]

Factor out a homogeneous type from an either of pairs.

Here, the homogeneous type is the first element of the pairs.

impl<A, B, T> Either<(A, T), (B, T)>[src]

pub fn factor_second(self) -> (Either<A, B>, T)[src]

Factor out a homogeneous type from an either of pairs.

Here, the homogeneous type is the second element of the pairs.

impl<T> Either<T, T>[src]

pub fn into_inner(self) -> T[src]

Extract the value of an either over two equivalent types.
