Struct Termios

pub struct Termios { /* private fields */ }

Unix terminal I/O control structure.

The Termios structure is a thin wrapper for the OS-specific termios struct. The only safe way to obtain a Termios structure is to fill one from a file descriptor with Termios::from_fd(), after which it can be treated just like the POSIX termios struct. It provides access to the standard fields of the termios struct (c_iflag, c_oflag, c_cflag, c_lflag, and c_cc) through the Deref and DerefMut traits.

Example

The following is an example of how one might setup a file descriptor for a serial port:

use std::io;
use std::os::unix::io::RawFd;

fn setup_serial(fd: RawFd) -> io::Result<()> {
    use termios::*;

    let mut termios = try!(Termios::from_fd(fd));

    termios.c_cflag |= CREAD | CLOCAL;
    termios.c_lflag &= !(ICANON | ECHO | ECHOE | ECHOK | ECHONL | ISIG | IEXTEN);
    termios.c_oflag &= !OPOST;
    termios.c_iflag &= !(INLCR | IGNCR | ICRNL | IGNBRK);

    termios.c_cc[VMIN] = 0;
    termios.c_cc[VTIME] = 0;

    try!(cfsetspeed(&mut termios, B9600));
    try!(tcsetattr(fd, TCSANOW, &mut termios));

    Ok(())
}

Implementations

impl Termios

pub fn from_fd(fd: RawFd) -> Result<Self>

Creates a Termios structure based on the current settings of a file descriptor.

fd must be an open file descriptor for a terminal device.

Trait Implementations

impl Clone for Termios

fn clone(&self) -> Termios

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Termios

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Deref for Termios

type Target = termios

The resulting type after dereferencing.

fn deref(&self) -> &termios

Dereferences the value.

impl DerefMut for Termios

fn deref_mut(&mut self) -> &mut termios

Mutably dereferences the value.

impl PartialEq for Termios

fn eq(&self, other: &Termios) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
