pledge-rs

A Rust binding to OpenBSD's pledge(2) interface.

Usage

#[macro_use] extern crate pledge;
use pledge::{pledge, Promise, ToPromiseString};

fn foo() {
    match pledge![Stdio, RPath] {
        Err(_) => println!("Failed to pledge"),
        _ => ()
    }
}

This is equivalent to:

extern crate pledge;
use pledge::{pledge, Promise, ToPromiseString};

fn foo() {
    match pledge(&vec![Promise::Stdio, Promise::RPath].to_promise_string()) {
        Err(_) => println!("Failed to pledge"),
        _ => ()
    }
}

You may also provide promises directly as a string:

use pledge::pledge;

fn foo() {
    if pledge("stdio rpath").is_err() {
        panic!("Failed to pledge");
    }
}
