Struct transform_stream::AsyncTryStream

pub struct AsyncTryStream<T, E, G> { /* private fields */ }

Asynchronous stream of results

Implementations

impl<T, E, G> AsyncTryStream<T, E, G>

pub fn new<F>(f: F) -> Selfwhere
    F: FnOnce(Yielder<Result<T, E>>) -> G,

Constructs an AsyncTryStream by a factory function which returns a future.

Trait Implementations

impl<T: Debug, E: Debug, G: Debug> Debug for AsyncTryStream<T, E, G>

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

Formats the value using the given formatter.

impl<T, E, G> FusedStream for AsyncTryStream<T, E, G>where
    G: Future<Output = Result<(), E>>,

fn is_terminated(&self) -> bool

Returns true if the stream should no longer be polled.

impl<T, E, G> Stream for AsyncTryStream<T, E, G>where
    G: Future<Output = Result<(), E>>,

type Item = Result<T, E>

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.
