[][src]Struct futures_core::stream::StreamObj

pub struct StreamObj<'a, T>(_);

A custom trait object for polling streams, roughly akin to Box<dyn Stream<Item = T> + Send + 'a>.

This custom trait object was introduced for two reasons:

Methods

impl<'a, T> StreamObj<'a, T>
[src]

Create a StreamObj from a custom trait object representation.

Trait Implementations

impl<'a, T> Stream for StreamObj<'a, T>
[src]

Values yielded by the stream.

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. Read more

[src]

Performs the conversion.

impl<'a, F: Stream<Item = ()> + Send + 'a> From<Pin<Box<F>>> for StreamObj<'a, ()>
[src]
