Trait in_place::entry::RemovableOccupiedEntry

pub trait RemovableOccupiedEntry<'c>: OccupiedEntry<'c> {
    type Removed: 'c;
    fn remove(self) -> (Self::Value, Self::Removed);

    fn remove_value(self) -> Self::Value { ... }
    fn vacate(self) -> (Self::Value, Self::Removed)
    where
        Self::Removed: VacantEntry<'c, Occupied = Self>,
    { ... }
}

A trait to represent an OccupiedEntry that can be removed from the collection.

This will consume the OccupiedEntry, returning RemovableOccupiedEntry::Removed.
