tokio-command-fds
A library for passing arbitrary file descriptors when spawning child processes.
(Forked from https://github.com/google/command-fds to add support for tokio)
Example
#[tokio::main(flavor="current_thread")]
async fn main() {
use tokio_command_fds::{CommandFdExt, FdMapping};
use std::fs::File;
use std::os::unix::io::AsRawFd;
use tokio::process::Command;
let file = File::open("Cargo.toml").unwrap();
let mut command = tokio::process::Command::new("ls");
command.arg("-l").arg("/proc/self/fd");
command
.fd_mappings(vec![
FdMapping {
parent_fd: file.as_raw_fd(),
child_fd: 3,
},
FdMapping {
parent_fd: 0,
child_fd: 5,
},
])
.unwrap();
let mut child = command.spawn().unwrap();
child.wait().await.unwrap();
}
