Crate ptyprocess[−][src]
Expand description
Ptyprocess library provides an interface for a PTY/TTY.
The entry point to the library is a PtyProcess.
The library provides a sync
and async
IO operations for communication.
To be able to use async
you must to provide a feature flag [async]
and turn off default features default-features = false
.
The library was developed as a backend for a https://github.com/zhiburt/expectrl.
If you’re interested in a high level operations may you’d better take a look at zhiburt/expectrl
.
Example
ⓘ
use ptyprocess::PtyProcess;
use std::process::Command;
use std::io::{Read, Write};
// spawn a cat process
let mut process = PtyProcess::spawn(Command::new("cat")).expect("failed to spawn a process");
// write message to cat.
process.write_all(b"hello cat\n").expect("failed to write");
// read what cat produced.
let mut buf = vec![0; 128];
let size = process.read(&mut buf).expect("failed to read");
assert_eq!(&buf[..size], b"hello cat\r\n");
// stop process
let sucess = process.exit(true).expect("failed to exit");
assert_eq!(sucess, true);
Async
Example
ⓘ
use ptyprocess::PtyProcess;
use std::process::Command;
// spawns a cat process
let mut process = PtyProcess::spawn(Command::new("cat")).expect("failed to spawn a process");
// sends line to cat
process.send_line("hello cat").await.expect("failed writing");
