pub struct SkipWhile<St, Fut, F> where
    St: Stream,  { /* fields omitted */ }

[−] Expand description

A stream combinator which skips elements of a stream while a predicate holds.

This structure is produced by the Stream::skip_while method.

Methods

impl<St, Fut, F> SkipWhile<St, Fut, F> where     F: FnMut(&<St as Stream>::Item) -> Fut,     Fut: Future<Output = bool>,     St: Stream,

Important traits for &'a mut I

impl<'a, I> Iterator for &'a mut I where
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;impl<'a, R> Read for &'a mut R where
    R: Read + ?Sized, impl<'a, W> Write for &'a mut W where
    W: Write + ?Sized, 

pub fn get_ref(&self) -> &St

[−]

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

Important traits for &'a mut I

impl<'a, I> Iterator for &'a mut I where
    I: Iterator + ?Sized,  type Item = <I as Iterator>::Item;impl<'a, R> Read for &'a mut R where
    R: Read + ?Sized, impl<'a, W> Write for &'a mut W where
    W: Write + ?Sized, 

pub fn get_mut(&mut self) -> &mut St

[−]

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) -> St

[−]

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.

Trait Implementations

impl<St, Fut, F> Unpin for SkipWhile<St, Fut, F> where     Fut: Unpin,     St: Unpin + Stream,

impl<St, Fut, F> Debug for SkipWhile<St, Fut, F> where     F: Debug,     Fut: Debug,     St: Debug + Stream,     <St as Stream>::Item: Debug,

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

[−]

Formats the value using the given formatter.

impl<St, Fut, F> Stream for SkipWhile<St, Fut, F> where     F: FnMut(&<St as Stream>::Item) -> Fut,     Fut: Future<Output = bool>,     St: Stream,

[+]

type Item = <St as Stream>::Item

Values yielded by the stream.

fn poll_next(     self: PinMut<SkipWhile<St, Fut, F>>,     cx: &mut Context ) -> Poll<Option<<St as Stream>::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.
