[−][src]Enum smallmap::entry::Entry
Represents a space in a Map
that may or may not contains a value.
Variants
Vacant(VacantEntry<'a, K, V>)
This entry slot does not yet contain a value
Occupied(OccupiedEntry<'a, K, V>)
This entry slot does contain a value
Implementations
impl<'a, K, V> Entry<'a, K, V> where
K: Collapse,
[src]
K: Collapse,
pub fn and_modify<F: FnOnce(&mut V)>(self, f: F) -> Entry<'a, K, V>
[src]
Run this closure on a mutable reference to the internal value if it is present, otherwise do nothing.
pub fn key(&self) -> &K
[src]
A reference to the key
pub fn or_insert_with<F: FnOnce() -> V>(self, with: F) -> &'a mut V
[src]
Insert into the entry if it is empty the value returned by the closure and return a mutable reference to the new value, otherwise return a mutable reference to the already present value.
pub fn or_insert(self, value: V) -> &'a mut V
[src]
Insert into the entry this value if it is empty and return a mutable reference to the new value, otherwise return a mutable reference to the already present value.
impl<'a, K, V> Entry<'a, K, V> where
K: Collapse,
V: Default,
[src]
K: Collapse,
V: Default,
pub fn or_default(self) -> &'a mut V
[src]
Insert into the entry the default value if it is empty and return a mutable reference to the new value, otherwise return a mutable reference to the already present value.
