Crate priority_set

A fixed size priority set suitable for no_std use.

Example:

#[derive(PartialEq, Debug)]
enum Command {
    QueryServerA,
    QueryServerB,
}

fn main() {
    // Create a priority set with 10 slots
    let mut p: PrioritySet<Command, 10> = PrioritySet::new();

    // Insert two items
    p.insert(Priority(10), Command::QueryServerA);
    p.insert(Priority(20), Command::QueryServerB);
    p.insert(Priority(30), Command::QueryServerA);

    // We inserted a duplicate command, so its priority was updated, but no new item was added
    assert_eq!(p.len(), 2);

    // Pops the highest priority item, which is QueryServerA with Priority(30)
    assert_eq!(p.pop(), Some(Command::QueryServerA));
    assert_eq!(p.pop(), Some(Command::QueryServerB));
    assert_eq!(p.pop(), None);
}
