Termios Rust Bindings

The termios crate provides safe bindings for the Rust programming language to the terminal I/O interface implemented by Unix operating systems. The safe bindings are a small wrapper around the raw C functions, which converts integer return values to std::io::Result to indicate success or failure. The raw C functions are available in the termios::ffi module, but must be called within an unsafe block.

Dependencies

In order to use the termios crate, you must have a native libc library that implements the termios API. This should be available on any recent version of OSX or Linux using glibc.

Usage

Add termios as a dependency in Cargo.toml:

[dependencies]
termios = "0.0.5"
libc = "0.1.5"

Import the termios crate and any symbols needed from termios. You will also probably need libc::c_int for file descriptors and std::io::Result to propagate errors.

extern crate termios;
extern crate libc;

use std::io;
use libc::c_int;
use termios::*;

fn setup_fd(fd: c_int) -> io::Result<()> {
  let mut tios = try!(Termios::from_fd(fd));

  tios.c_iflag = IGNPAR | IGNBRK;
  tios.c_oflag = 0;
  tios.c_cflag = CS8 | CREAD | CLOCAL;
  tios.c_lflag = 0;

  try!(cfsetspeed(&mut tios, B9600));
  try!(tcsetattr(fd, TCSANOW, &tios));
  try!(tcflush(fd, TCIOFLUSH));

  Ok(());
}
