Extension trait for AsyncRead.

Provided Methods§

source

fn try_read_exact<'life0, 'async_trait, const N: usize>( &'life0 mut self ) -> Pin<Box<dyn Future<Output = Result<Option<[u8; N]>>> + Send + 'async_trait>>where Self: Send + 'async_trait, 'life0: 'async_trait,

Reads the exact number of bytes, like read_exact, but returns None if it gets EOF at the start of the read. In other words, this is the “all or nothing” version of read.
