Struct OutputAsync

pub struct OutputAsync { /* private fields */ }

Future returned by the CommandExt::output_async method.

This future is mostly equivalent to spawning a process and then calling wait_with_output on it internally. This can be useful to simply spawn a process, collecting all of its output and its exit status.

Trait Implementations

impl Debug for OutputAsync

fn fmt(&self, fmt: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Future for OutputAsync

type Item = Output

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

type Error = Error

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

fn poll(&mut self) -> Poll<Output, Error>

fn from_err<E>(self) -> FromErr<Self, E>

where E: From<Self::Error>, 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>) -> B, B: IntoFuture, Self: Sized,

fn or_else<F, B>(self, f: F) -> OrElse<Self, B, F>

where F: FnOnce(Self::Error) -> B, B: IntoFuture<Item = Self::Item>, Self: Sized,

Execute another future if this one resolves with an error.

fn select<B>(self, other: B) -> Select<Self, <B as IntoFuture>::Future>

where B: IntoFuture<Item = Self::Item, Error = Self::Error>, Self: Sized,

Waits for either one of two futures to complete.

fn select2<B>(self, other: B) -> Select2<Self, <B as IntoFuture>::Future>

where B: IntoFuture, Self: Sized,

Waits for either one of two differently-typed futures to complete.

fn join<B>(self, other: B) -> Join<Self, <B as IntoFuture>::Future>

where B: IntoFuture<Error = Self::Error>, Self: Sized,

Joins the result of two futures, waiting for them both to complete.

fn join3<B, C>( self, b: B, c: C, ) -> Join3<Self, <B as IntoFuture>::Future, <C as IntoFuture>::Future>

where B: IntoFuture<Error = Self::Error>, C: IntoFuture<Error = Self::Error>, Self: Sized,

Same as join, but with more futures.

fn join4<B, C, D>( self, b: B, c: C, d: D, ) -> Join4<Self, <B as IntoFuture>::Future, <C as IntoFuture>::Future, <D as IntoFuture>::Future>

where B: IntoFuture<Error = Self::Error>, C: IntoFuture<Error = Self::Error>, D: IntoFuture<Error = Self::Error>, Self: Sized,

where B: IntoFuture<Error = Self::Error>, C: IntoFuture<Error = Self::Error>, D: IntoFuture<Error = Self::Error>, E: IntoFuture<Error = Self::Error>, Self: Sized,

Same as join, but with more futures.

fn into_stream(self) -> IntoStream<Self>

where Self: Sized,

Convert this future into a single element stream.

fn flatten(self) -> Flatten<Self>

where Self::Item: IntoFuture, <Self::Item as IntoFuture>::Error: From<Self::Error>, Self: Sized,

fn flatten_stream(self) -> FlattenStream<Self>

where Self::Item: Stream<Error = Self::Error>, Self: Sized,

Flatten the execution of this future when the successful result of this future is a stream.

fn fuse(self) -> Fuse<Self>

where Self: Sized,

Fuse a future such that poll will never again be called once it has completed.

fn inspect<F>(self, f: F) -> Inspect<Self, F>

where F: FnOnce(&Self::Item), Self: Sized,

fn catch_unwind(self) -> CatchUnwind<Self>

where Self: Sized + UnwindSafe,

fn shared(self) -> Shared<Self>

where Self: Sized,
