[][src]Struct futures_core::stream::LocalStreamObj

pub struct LocalStreamObj<'a, T> { /* fields omitted */ }

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

This custom trait object was introduced for two reasons:

Methods

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

Create a LocalStreamObj from a custom trait object representation.

Converts the LocalStreamObj into a StreamObj To make this operation safe one has to ensure that the UnsafeStreamObj instance from which this LocalStreamObj was created actually implements Send.

Trait Implementations

impl<'a, T> Stream for LocalStreamObj<'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

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

Performs the conversion.

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

Performs the conversion.

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