Trait Read

pub trait Read {
    type Error: ReadError;

    // Required method
    fn read_slice(&mut self, buf: &mut [u8]) -> Result<usize, Self::Error>;
}

This trait allows reading bytes from a source.

Types implementing this trait are called “readers”.

Required Associated Types

type Error: ReadError

Error type for IO operations involving the reader.

Required Methods

fn read_slice(&mut self, buf: &mut [u8]) -> Result<usize, Self::Error>

Read some bytes into the slice buf.

This function is the lower level building block of the other read_* methods. It reads bytes into buf and reports back to the caller how many bytes it read.
