Enum Entry

Source

pub enum Entry<'b, 'a, K, V, S = RapidBuildHasher>where
    K: Eq + Hash + Clone + Send + Sync + 'static,
    V: Clone + Send + Sync + 'static,
    S: BuildHasher + Send + Sync + 'static,{
    Occupied(OccupiedEntry<'b, 'a, K, V, S>),
    Vacant(VacantEntry<'b, 'a, K, V, S>),
}

Expand description

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

Variants§

§

Occupied(OccupiedEntry<'b, 'a, K, V, S>)

An occupied entry.

§

Vacant(VacantEntry<'b, 'a, K, V, S>)

A vacant entry.

Implementations§

Source §

impl<'b, 'a, K, V, S> Entry<'b, 'a, K, V, S>
where K: Eq + Hash + Clone + Send + Sync + 'static, V: Clone + Send + Sync + 'static, S: BuildHasher + Send + Sync + 'static,

Source

pub fn or_insert_with<F: FnOnce() -> V>( self, default: F, ) -> OccupiedEntry<'b, 'a, K, V, S>

Ensures a value is in the entry by inserting the result of the default function if empty, and returns an occupied entry.
