Trait Scheduler

pub trait Scheduler {
    // Required methods
    fn activate(&mut self, path: &[usize]);
    fn extensions(&mut self, path: &[usize], dest: &mut Vec<usize>);
}

Methods required to act as a timely scheduler.

The core methods are the activation of “paths”, sequences of integers, and the enumeration of active paths by prefix. A scheduler may delay the report of a path indefinitely, but it should report at least one extension for the empty path &[] or risk parking the worker thread without a certain unpark.

There is no known harm to “spurious wake-ups” where a not-active path is returned through extensions().

Required Methods

fn activate(&mut self, path: &[usize])

Mark a path as immediately scheduleable.

fn extensions(&mut self, path: &[usize], dest: &mut Vec<usize>)

Populates dest with next identifiers on active extensions of path.

This method is where a scheduler is allowed to exercise some discretion, in that it does not need to present all extensions, but it can instead present only those that the runtime should schedule.
