[−][src]Struct abi_stable::std_types::map::ROccupiedEntry
A handle into an occupied entry in a map,always a variant of an REntry.
Methods
impl<'a, K, V> ROccupiedEntry<'a, K, V>[src]
pub fn key(&self) -> &K[src]
Gets the key of the entry.
pub fn get(&self) -> &V[src]
Gets a reference to the value in the entry.
pub fn get_mut(&mut self) -> &mut V[src]
Gets a mutable reference to the value in the entry.
To borrow with the lifetime of the map,use ROccupiedEntry::into_mut.
pub fn into_mut(self) -> &'a mut V[src]
Gets a mutable reference to the value in the entry,
that borrows with the lifetime of the map instead of from this ROccupiedEntry.
pub fn insert(&mut self, value: V) -> V[src]
Replaces the current value of the entry with value,returning the previous value.
pub fn remove(self) -> V[src]
Removes the entry from the map,returns the value.
