[−][src]Enum typemap_rev::Entry

pub enum Entry<'a, K> where
    K: TypeMapKey,  {
    Occupied(OccupiedEntry<'a, K>),
    Vacant(VacantEntry<'a, K>),
}

A view into a single entry in the TypeMap, which may either be vacant or occupied.

This heavily mirrors the official Entry API in the standard library, but not all of it is provided due to implementation restrictions. Please refer to its documentations.

Variants

Occupied(OccupiedEntry<'a, K>)
Vacant(VacantEntry<'a, K>)
