Expand description

Implemented as an extension trait, adding utility methods to all AsyncRead types. Callers will tend to import this trait instead of AsyncRead.

Provided Methods§

source

fn by_ref(&mut self) -> &mut Self
where Self: Sized,

Creates a “by reference” adaptor for this instance of AsyncRead.

The returned adapter also implements AsyncRead and will simply borrow this current reader.

source

async fn read_exact<T: IoBufMut>(&mut self, buf: T) -> BufResult<(), T>

Read the exact number of bytes required to fill the buf.

source

async fn read_to_end(&mut self, buf: Vec<u8>) -> BufResult<usize, Vec<u8>>

Read all bytes until underlying reader reaches EOF.

source

async fn read_vectored_exact<T: IoVectoredBufMut>( &mut self, buf: T, ) -> BufResult<(), T>

Read the exact number of bytes required to fill the vectored buf.

source

fn take(self, limit: u64) -> Take<Self>
where Self: Sized,

Creates an adaptor which reads at most limit bytes from it.

This function returns a new instance of AsyncRead which will read at most limit bytes, after which it will always return EOF (Ok(0)). Any read errors will not count towards the number of bytes read and future calls to read() may succeed.
