Enum actix::fut::Either

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

Combines two different futures yielding the same item and error types into a single type.

Variants

A(A)

First branch of the type

B(B)

Second branch of the type

Methods

impl<T, A, B> Either<(T, A), (T, B)>

pub fn split(self) -> (T, Either<A, B>)

Splits out the homogeneous type from an either of tuples.

This method is typically useful when combined with the Future::select2 combinator.

Trait Implementations

impl<A: Debug, B: Debug> Debug for Either<A, B>

fn fmt(&self, f: &mut Formatter) -> Result

Formats the value using the given formatter.

impl<A, B> ActorFuture for Either<A, B> where     A: ActorFuture,     B: ActorFuture<Item = A::Item, Error = A::Error, Actor = A::Actor>,

type Item = A::Item

The type of value that this future will resolved with if it is successful.

type Error = A::Error

The type of error that this future will resolve with if it fails in a normal fashion.

type Actor = A::Actor

The actor within which this future runs

fn poll(     &mut self,     act: &mut A::Actor,     ctx: &mut <A::Actor as Actor>::Context ) -> Poll<A::Item, B::Error>

fn map<F, U>(self, f: F) -> Map<Self, F> where     F: FnOnce(Self::Item, &mut Self::Actor, &mut <Self::Actor as Actor>::Context) -> U,     Self: Sized,

Map this future's result to a different type, returning a new future of the resulting type.

fn map_err<F, E>(self, f: F) -> MapErr<Self, F> where     F: FnOnce(Self::Error, &mut Self::Actor, &mut <Self::Actor as Actor>::Context) -> E,     Self: Sized,

Map this future's error to a different error, returning a new future.

fn drop_err(self) -> DropErr<Self> where     Self: Sized,

Drop this future's error, returning a new future.

fn from_err<E: From<Self::Error>>(self) -> FromErr<Self, E> where     Self: Sized,

Map this future's error to any error implementing From for this future's Error, returning a new future.

fn then<F, B>(self, f: F) -> Then<Self, B, F> where     F: FnOnce(Result<Self::Item, Self::Error>, &mut Self::Actor, &mut <Self::Actor as Actor>::Context) -> B,     B: IntoActorFuture<Actor = Self::Actor>,     Self: Sized,

Chain on a computation for when a future finished, passing the result of the future to the provided closure f.

fn and_then<F, B>(self, f: F) -> AndThen<Self, B, F> where     F: FnOnce(Self::Item, &mut Self::Actor, &mut <Self::Actor as Actor>::Context) -> B,     B: IntoActorFuture<Error = Self::Error, Actor = Self::Actor>,     Self: Sized,

Execute another future after this one has resolved successfully.

fn timeout(self, timeout: Duration, err: Self::Error) -> Timeout<Self> where     Self: Sized,

Add timeout to futures chain.
