pub enum Entry<'a, K> {
Occupied(OccupiedEntry<'a, K>),
Vacant(VacantEntry<'a, K>),
}
client
only.Expand description
A view into a single object, with enough context to create or update it
See Api::entry
for more information.
Variants
Occupied(OccupiedEntry<'a, K>)
An object that either exists on the server, or has been created locally (and is awaiting synchronization)
Vacant(VacantEntry<'a, K>)
An object that does not exist
Implementations
sourceimpl<'a, K> Entry<'a, K>
impl<'a, K> Entry<'a, K>
sourcepub fn get(&self) -> Option<&K>
pub fn get(&self) -> Option<&K>
Borrow the object, if it exists (on the API, or queued for creation using Entry::or_insert
)
sourcepub fn get_mut(&mut self) -> Option<&mut K>
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.
sourcepub fn and_modify(self, f: impl FnOnce(&mut K)) -> Self
pub fn and_modify(self, f: impl FnOnce(&mut K)) -> Self
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.
sourcepub fn or_insert(self, default: impl FnOnce() -> K) -> OccupiedEntry<'a, K> where
K: Resource,
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.
