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");
