Vorarbeiter, a small process supervisor

vorarbeiter::Supervisor shuts down processes it owns on Drop by sending a SIGTERM first, followed by a SIGKILL:

use std::process;

// The default kill timeout is 10 seconds, which is fine here.
let mut supervisor = vorarbeiter::Supervisor::default();

// Spawns three new child processes and adds them to the supervisor.
for _ in 0..3 {
    let child = process::Command::new("my-subcommand").spawn().unwrap();
    supervisor.add_child(child);
}

// Terminate all child processes.
drop(supervisor);

See the documentation for details.

lib.rs:

A supervisor for processes that allow clean shutdowns.

See Supervisor for the core functionality. Real applications will likely want to use setup_term_flag as well.

Example

use std::process;

// The default kill timeout is 10 seconds, which is fine here.
let mut supervisor = vorarbeiter::Supervisor::default();

// Spawns three new child processes and adds them to the supervisor.
for _ in 0..3 {
    let child = process::Command::new("my-subcommand").spawn().unwrap();
    supervisor.add_child(child);
}

// Terminate all child processes, waiting for each to be completed or killed.
drop(supervisor);
