Struct Split

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())
}

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.

Returns the argument unchanged.

Calls U::from(self).

That is, this conversion is whatever the implementation of From<T> for U chooses to do.
