source§fn read(&mut self, size: usize) -> Result<Bytes, StreamError>
fn read(&mut self, size: usize) -> Result<Bytes, StreamError>
Reads up to
size
bytes, returning a buffer holding these bytes on
success. Read moresource§fn cancel<'life0, 'async_trait>(

fn cancel<'life0, 'async_trait>(
&'life0 mut self,
) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>where
Self: 'async_trait,
'life0: 'async_trait,
Cancel any asynchronous work and wait for it to wrap up.
