Struct actix_web::actix::fut::StreamFinish

#[must_use = "streams do nothing unless polled"]
pub struct StreamFinish<S>(_);

A combinator used to convert stream into a future, future resolves when stream completes.

This structure is produced by the ActorStream::finish method.

Trait Implementations

impl<S> ActorFuture for StreamFinish<S> where
    S: ActorStream, 

type Item = ()

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

type Error = <S as ActorStream>::Error

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

type Actor = <S as ActorStream>::Actor

The actor within which this future runs

fn poll(
    &mut self,
    act: &mut <S as ActorStream>::Actor,
    ctx: &mut <<S as ActorStream>::Actor as Actor>::Context
) -> Result<Async<()>, <S as ActorStream>::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, 

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, 

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

fn drop_err(self) -> DropErr<Self>

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

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

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
    B: IntoActorFuture<Actor = Self::Actor>,
    F: FnOnce(Result<Self::Item, Self::Error>, &mut Self::Actor, &mut <Self::Actor as Actor>::Context) -> B, 

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
    B: IntoActorFuture<Error = Self::Error, Actor = Self::Actor>,
    F: FnOnce(Self::Item, &mut Self::Actor, &mut <Self::Actor as Actor>::Context) -> B, 

Execute another future after this one has resolved successfully.

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

Add timeout to futures chain.

impl<S> Debug for StreamFinish<S> where
    S: Debug, 

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

Formats the value using the given formatter.
