Enum RawEntryMut 

pub enum RawEntryMut<'a, K, V> {
    Occupied(RawOccupiedEntryMut<'a, K, V>),
    Vacant(RawVacantEntryMut<'a, K, V>),
}

Result of KevyMap::raw_entry_mut.

Mirrors hashbrown::hash_map::RawEntryMut: an Occupied arm grants read / mutate / consume access to the existing entry; a Vacant arm can be filled with insert(k, v). The defining property — and the reason this API exists distinct from get_mut — is that RawOccupiedEntryMut::remove consumes self, which releases the outstanding borrow on the map and lets the caller perform the deletion within the same borrow scope.

Variants

Occupied(RawOccupiedEntryMut<'a, K, V>)

The key was present; gives read / mutate / consume access.

Vacant(RawVacantEntryMut<'a, K, V>)

The key was absent; insert(k, v) writes a new entry.
