[][src]Struct futures::stream::FilterMap

#[must_use = "streams do nothing unless polled"]
pub struct FilterMap<S, F> { /* fields omitted */ }

A combinator used to filter the results of a stream and simultaneously map them to a different type.

This structure is returned by the Stream::filter_map method.

Methods

impl<S, F> FilterMap<S, F>[src]

pub fn get_ref(&self) -> &S[src]

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

pub fn get_mut(&mut self) -> &mut S[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.

pub fn into_inner(self) -> S[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.
