Trait Input

pub trait Input {
    type Error;

    // Required method
    fn read(&mut self, into: &mut [u8]) -> Result<(), Self::Error>;

    // Provided method
    fn read_byte(&mut self) -> Result<u8, Self::Error> { ... }
}

Trait that allows reading of data into a slice.

Required Associated Types

type Error

Provided Methods

fn read_byte(&mut self) -> Result<u8, Self::Error>

Read a single byte from the input.
