}

Storage trait that maintains key package secrets.

Required Associated Types

type Error: IntoAnyError

Error type that the underlying storage mechanism returns on internal failure.

Required Methods

fn delete(&mut self, id: &[u8]) -> Result<(), Self::Error>

Delete KeyPackageData referenced by id.

This function is called automatically when the key package referenced by id is used to successfully join a group.

Warning

KeyPackageData internally contains secret key values. The provided delete mechanism should securely erase data.

fn insert( &mut self, id: Vec<u8>, pkg: KeyPackageData ) -> Result<(), Self::Error>

Store KeyPackageData that can be accessed by id in the future.

This function is automatically called whenever a new key package is created.

fn get(&self, id: &[u8]) -> Result<Option<KeyPackageData>, Self::Error>

Retrieve KeyPackageData by its id.

None should be returned in the event that no key packages are found that match id.
