fn get(&self, k: &Key) -> Option<Cow<'_, Record>>

Gets a record from the store, given its key.

fn put(&mut self, r: Record) -> Result<()>

Puts a record into the store.

fn remove(&mut self, k: &Key)

Removes the record with the given key from the store.

fn records(&self) -> Self::RecordsIter<'_>

Gets an iterator over all (value-) records currently stored.

fn add_provider(&mut self, record: ProviderRecord) -> Result<()>

Adds a provider record to the store.

fn providers(&self, key: &Key) -> Vec<ProviderRecord>

Gets a copy of the stored provider records for the given key.

fn provided(&self) -> Self::ProvidedIter<'_>
