Trait system_interface::io::ReadReady

pub trait ReadReady {
    // Required method
    fn num_ready_bytes(&self) -> Result<u64>;
}

Extension for readable streams that can indicate the number of bytes ready to be read immediately.

Required Methods

fn num_ready_bytes(&self) -> Result<u64>

Return the number of bytes which are ready to be read immediately.

The returned number may be greater than the number of bytes actually readable if the end of the stream is known to be reachable without blocking.
