Trait gjio::AsyncRead [−] [src]

pub trait AsyncRead {
    fn try_read<T>(
        &mut self, 
        buf: T, 
        min_bytes: usize
    ) -> Promise<(T, usize), Error>
    where
        T: AsMut<[u8]>;

    fn read<T>(
        &mut self, 
        buf: T, 
        min_bytes: usize
    ) -> Promise<(T, usize), Error>
    where
        T: AsMut<[u8]>,
    { ... }
}

A nonblocking input bytestream.

Required Methods

Attempts to read buf.len() bytes from the stream, writing them into buf. Returns the modified buf,and the number of bytes actually read. Returns as soon as min_bytes are read or EOF is encountered.

Provided Methods

Like try_read(), but returns an error if EOF is encountered before min_bytes can be read.
