Capability to yield Keys

Required Methods

fn next<M: KeyLookup + ?Sized>(&mut self) -> Result<usize, Traversal>

Look up the next key in a KeyLookup and convert to usize index.

fn is_empty(&mut self) -> bool

Return whether there are more keys.

This may mutate and consume remaining keys.

Object Safety

This trait is not object safe.
