Trait PriorityLevel

pub trait PriorityLevel {
    // Required method
    fn level(&self) -> usize;
}

Required trait on OrderedPool entries that allows ordering.

Priority levels follow the conventions common with schedulers: 0 is the highest priority, and will only get evicted if the cache is full with other entries of the same priority. Larger numeric values indicate increasingly lower priority.

Required Methods

fn level(&self) -> usize

Calculate the priority of the instance

An instance’s priority level may change while being mutated; OrderedPool will account for that.

The level should not change due to global effects (or internal mutability, if shared access is later implemented). If it does, the ordering of an OrderedPool containing it may become arbitrary, even after the element whose level changed has been removed.
