netns - network namespaces in Rust

The netns crate provides a simple and intuitive interface for handling network namespaces in Rust. It should be noted that since the switching of namespace requires privileged authority, the authority requirements for compliance should be met in practice.

Quick Start

To use netns, add the dependencies to your Cargo.toml

[dependencies]
netns = { git = 'https://github.com/inkhare/netns', branch = 'stable' }

Testing (requires root):

cargo run --example test

Example

use std::process::Command;

use netns::{apply_in_ns, ExecStatus};

fn main() {
    let closeure = || {
        let output = Command::new("sh").arg("-c").arg("ip a").output();
        println!("ip a = {:?}", output);
        ExecStatus::Success(0)
    };

    // 2667 is the namespace pid
    apply_in_ns(2667, closeure);
}

NOTE

This library is verified to work in rustc 1.51.0 (nightly), and the support of other versions needs more testing.
