Stream for the into_stream method.

Implementations

impl<St> IntoStream<St>[−]

pub fn get_ref(&self) -> &St[−]

Acquires a reference to the underlying sink or stream that this combinator is pulling from.

pub fn get_mut(&mut self) -> &mut St[−]

Acquires a mutable reference to the underlying sink or stream that this combinator is pulling from.

Note that care must be taken to avoid tampering with the state of the sink or stream which may otherwise confuse this combinator.

pub fn get_pin_mut(self: Pin<&mut Self>) -> Pin<&mut St>[−]

Acquires a pinned mutable reference to the underlying sink or stream that this combinator is pulling from.

Note that care must be taken to avoid tampering with the state of the sink or stream which may otherwise confuse this combinator.

pub fn into_inner(self) -> St[−]

Consumes this combinator, returning the underlying sink or stream.

Note that this may discard intermediate state of this combinator, so care should be taken to avoid losing resources when this is called.

Trait Implementations

impl<St: Debug> Debug for IntoStream<St>[+]

[+] Show hidden undocumented items

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

Formats the value using the given formatter.

impl<St: TryStream + FusedStream> FusedStream for IntoStream<St>[+]

[+] Show hidden undocumented items

fn is_terminated(&self) -> bool[−]

Returns true if the stream should no longer be polled.

impl<S: Sink<Item>, Item> Sink<Item> for IntoStream<S>[+]

[+] Show hidden undocumented items

type Error = S::Error

The type of value produced by the sink when an error occurs.

fn poll_ready(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>
) -> Poll<Result<(), Self::Error>>[−]

Attempts to prepare the Sink to receive a value.

fn start_send(self: Pin<&mut Self>, item: Item) -> Result<(), Self::Error>[−]

Begin the process of sending a value to the sink. Each call to this function must be preceded by a successful call to poll_ready which returned Poll::Ready(Ok(())).

fn poll_flush(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>
) -> Poll<Result<(), Self::Error>>[−]

Flush any remaining output from this sink.

fn poll_close(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>
) -> Poll<Result<(), Self::Error>>[−]

Flush any remaining output and close this sink, if necessary.

impl<St: TryStream> Stream for IntoStream<St>[+]

[+] Show hidden undocumented items

type Item = Result<St::Ok, St::Error>

Values yielded by the stream.

fn poll_next(
    self: Pin<&mut Self>,
    cx: &mut Context<'_>
) -> Poll<Option<Self::Item>>[−]

Attempt to pull out the next value of this stream, registering the current task for wakeup if the value is not yet available, and returning None if the stream is exhausted.

fn size_hint(&self) -> (usize, Option<usize>)[−]

Returns the bounds on the remaining length of the stream.
