[][src]Struct futures::stream::Fuse

#[must_use = "streams do nothing unless polled"]
pub struct Fuse<St> { /* fields omitted */ }

Stream for the fuse method.

Methods

impl<St> Fuse<St>[src]

pub fn is_done(&self) -> bool[src]

Returns whether the underlying stream has finished or not.

If this method returns true, then all future calls to poll are guaranteed to return None. If this returns false, then the underlying stream is still in use.

Important traits for &'_ mut F
pub fn get_ref(&self) -> &St[src]

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

Important traits for &'_ mut F
pub fn get_mut(&mut self) -> &mut St[src]

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

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

Important traits for Pin<P>
pub fn get_pin_mut(self: Pin<&mut Fuse<St>>) -> Pin<&mut St>[src]

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

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

pub fn into_inner(self) -> St[src]

Consumes this combinator, returning the underlying stream.

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