Enum Entry

pub enum Entry<'a, T: BiHashItem, S = DefaultHashBuilder, A: Allocator = Global> {
    Vacant(VacantEntry<'a, T, S, A>),
    Occupied(OccupiedEntry<'a, T, S, A>),
}

An implementation of the Entry API for BiHashMap.

Variants

Vacant(VacantEntry<'a, T, S, A>)

A vacant entry: none of the provided keys are present.

Occupied(OccupiedEntry<'a, T, S, A>)

An occupied entry where at least one of the keys is present in the map.

Implementations

impl<'a, T: BiHashItem, S: Clone + BuildHasher, A: Allocator> Entry<'a, T, S, A>

pub fn or_insert(self, default: T) -> OccupiedEntryMut<'a, T, S>

Ensures a value is in the entry by inserting the default if empty, and returns a mutable reference to the value in the entry.

Panics

Panics if the key hashes to a different value than the one passed into BiHashMap::entry.

pub fn or_insert_with<F: FnOnce() -> T>( self, default: F, ) -> OccupiedEntryMut<'a, T, S>

Ensures a value is in the entry by inserting the result of the default function if empty, and returns a mutable reference to the value in the entry.

Panics

Panics if the key hashes to a different value than the one passed into BiHashMap::entry.

pub fn and_modify<F>(self, f: F) -> Self

where F: FnMut(RefMut<'_, T, S>),

Provides in-place mutable access to occupied entries before any potential inserts into the map.

F is called for each entry that matches the provided keys.
