Extended functions for reading bytes

Associated Types

Required methods

pub fn read_exact<'a>(&'a mut self, buf: &'a mut [u8]) -> Self::ExactFuture

Read bytes from the device

This reads exactly buf.len() bytes from the device.

pub fn read_line<'a>(&'a mut self, buf: &'a mut String) -> Self::LineFuture

Read a line from the device

This reads bytes from the device into the passed String until it reaches a newline (0x0A). The newline will also be included in the output string.
