Trait ChildExt 

pub trait ChildExt: Sealed {
    // Required method
    fn send_signal(&self, signal: i32) -> Result<()>;
}

🔬This is a nightly-only experimental API. (unix_send_signal #141975)

Available on non-Hermit and (Unix) and not ((WebAssembly and non-WASI, or Fortanix and SGX)) only.

Required Methods

fn send_signal(&self, signal: i32) -> Result<()>

🔬This is a nightly-only experimental API. (unix_send_signal #141975)

Sends a signal to a child process.

Errors

This function will return an error if the signal is invalid. The integer values associated with signals are implementation-specific, so it’s encouraged to use a crate that provides posix bindings.

Examples

#![feature(unix_send_signal)]

use std::{io, os::unix::process::ChildExt, process::{Command, Stdio}};

use libc::SIGTERM;

fn main() -> io::Result<()> {
    let child = Command::new("cat").stdin(Stdio::piped()).spawn()?;
    child.send_signal(SIGTERM)?;
    Ok(())
}
