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

```rust

[tokio::main(flavor="current_thread")]

async fn main() { use tokiocommandfds::{CommandFdExt, FdMapping}; use std::fs::File; use std::os::unix::io::AsRawFd; use tokio::process::Command;

// Open a file.
let file = File::open("Cargo.toml").unwrap();

// Prepare to run `ls -l /proc/self/fd` with some FDs mapped.
let mut command = tokio::process::Command::new("ls");
command.arg("-l").arg("/proc/self/fd");
command
    .fd_mappings(vec![
        // Map `file` as FD 3 in the child process.
        FdMapping {
            parent_fd: file.as_raw_fd(),
            child_fd: 3,
        },
        // Map this process's stdin as FD 5 in the child process.
        FdMapping {
            parent_fd: 0,
            child_fd: 5,
        },
    ])
    .unwrap();

// Spawn the child process.
let mut child = command.spawn().unwrap();
child.wait().await.unwrap();

} ```
