Struct hyper_static_server::tokio::io::Split

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

Splitter for the split method.

A Split can be turned into a Stream with SplitStream.

Implementations

impl<R> Split<R> where
    R: AsyncBufRead + Unpin, 

pub async fn next_segment(
    &'_ mut self
) -> Result<Option<Vec<u8, Global>>, Error>

Returns the next segment in the stream.

Examples

use tokio::io::AsyncBufReadExt;

let mut segments = my_buf_read.split(b'f');

while let Some(segment) = segments.next_segment().await? {
    println!("length = {}", segment.len())
}

impl<R> Split<R> where
    R: AsyncBufRead, 

pub fn poll_next_segment(
    self: Pin<&mut Split<R>>,
    cx: &mut Context<'_>
) -> Poll<Result<Option<Vec<u8, Global>>, Error>>

Polls for the next segment in the stream.

This method returns:

• Poll::Pending if the next segment is not yet available.
• Poll::Ready(Ok(Some(segment))) if the next segment is available.
• Poll::Ready(Ok(None)) if there are no more segments in this stream.
• Poll::Ready(Err(err)) if an IO error occurred while reading the next segment.

When the method returns Poll::Pending, the Waker in the provided Context is scheduled to receive a wakeup when more bytes become available on the underlying IO resource.

Note that on multiple calls to poll_next_segment, only the Waker from the Context passed to the most recent call is scheduled to receive a wakeup.

Trait Implementations

impl<R> Debug for Split<R> where
    R: Debug, 

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

Formats the value using the given formatter.
