Implementations

impl<'a, K> Entry<'a, K>

pub fn get(&self) -> Option<&K>

Borrow the object, if it exists (on the API, or queued for creation using Entry::or_insert)

pub fn get_mut(&mut self) -> Option<&mut K>

Borrow the object mutably, if it exists (on the API, or queued for creation using Entry::or_insert)

OccupiedEntry::commit must be called afterwards for any changes to be persisted.

pub fn and_modify(self, f: impl FnOnce(&mut K)) -> Entry<'a, K>

Let f modify the object, if it exists (on the API, or queued for creation using Entry::or_insert)

OccupiedEntry::commit must be called afterwards for any changes to be persisted.

pub fn or_insert(self, default: impl FnOnce() -> K) -> OccupiedEntry<'a, K>

where K: Resource,

Create a new object if it does not already exist

OccupiedEntry::commit must be called afterwards for the change to be persisted.
