rlimit

A simple wrapper for getrlimit and setrlimit.

Examples

Set resource limit

use rlimit::{setrlimit, Resource, Rlim};

const DEFAULT_SOFT_LIMIT: Rlim = Rlim::from_raw(4 * 1024 * 1024);
const DEFAULT_HARD_LIMIT: Rlim = Rlim::from_raw(8 * 1024 * 1024);
assert!(Resource::FSIZE.set(DEFAULT_SOFT_LIMIT, DEFAULT_HARD_LIMIT).is_ok());

let soft = Rlim::from_usize(16384);
let hard = soft * 2;
assert!(setrlimit(Resource::NOFILE, soft, hard).is_ok());

Get resource limit

use rlimit::{getrlimit, Resource, Rlim};

assert!(Resource::NOFILE.get().is_ok());
assert_eq!(getrlimit(Resource::CPU).unwrap(), (Rlim::INFINITY, Rlim::INFINITY));

Increase NOFILE limit

See the example nofile.
