Enable a type implementing AsyncRead to be consumed as if it were a Stream of Bytes.

Required Methods

fn reset<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait,

fn len(&self) -> usize

Provided Methods

fn is_empty(&self) -> bool

fn buffer_size(&self) -> usize

Trait Implementations

impl Stream for dyn SeekableStream

type Item = Result<Bytes, Error>

Values yielded by the stream.

fn poll_next( self: Pin<&mut Self>, cx: &mut Context<'_>, ) -> Poll<Option<Self::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.

fn size_hint(&self) -> (usize, Option<usize>)

Returns the bounds on the remaining length of the stream.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
