Module pwner::process

Holds the std implementation of a process.

All interactions are blocking, including the dropping of child processes (on *nix platforms).

Spawning an owned process

use std::process::Command;
use pwner::Spawner;

Command::new("ls").spawn_owned().expect("ls command failed to start");

Reading from the process

use std::io::Read;
use std::process::Command;
use pwner::Spawner;

let mut child = Command::new("ls").spawn_owned()?;
let mut output = String::new();
child.read_to_string(&mut output)?;

Writing to the process

use std::io::{Read, Write};
use std::process::Command;
use pwner::Spawner;

let mut child = Command::new("cat").spawn_owned()?;
child.write_all(b"hello\n")?;

let mut buffer = [0_u8; 10];
child.read(&mut buffer)?;

Graceful dropping

Note: Only available on *nix platforms.

When the owned process gets dropped, Process will try to kill it gracefully by sending a SIGINT and checking, without blocking, if the child has diesd. If the child is still running, it will block for 2seconds. If the process still doesn’t die, a SIGTERM is sent and another chance is given, until finally a SIGKILL is sent.

Structs

Duplex

An implementation of Process that uses std::process as the launcher.

Output

A readable handle for both the stdout and stderr of the child process.

Simplex

An implementation of Process that is stripped from any output pipes.
