Trait Device 

pub trait Device {
    type Error: Error;

    // Required methods
    fn read(&mut self) -> Result<Option<u8>, Self::Error>;
    fn write(&mut self, byte: u8) -> Result<(), Self::Error>;
    fn write_error(&mut self, byte: u8) -> Result<(), Self::Error>;
}

A device.

Required Associated Types

type Error: Error

An error.

Required Methods

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

Reads from standard input.

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

Writes to standard output.

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

Writes to standard error.

Dyn Compatibility

This trait is dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".

Implementations on Foreign Types
