Required methods

fn store_with_status(
    &self,
    k: &Self::KeyStoreId,
    v: &impl KeyStoreValue,
    s: Status
) -> Result<(), Self::Error> where
    Self: Sized, [src]

Store a value v that implements the KeyStoreValue trait for serialization with Status s under ID k.

Returns an error if storing fails.

fn store(
    &self,
    k: &Self::KeyStoreId,
    v: &impl KeyStoreValue
) -> Result<(), Self::Error> where
    Self: Sized, [src]

Store a value v that implements the KeyStoreValue trait for serialization for ID k. The status will always be Status::Extractable. To set the status of the value v use store_with_status.

Returns an error if storing fails.

fn read<V: KeyStoreValue>(&self, k: &Self::KeyStoreId) -> Result<V, Self::Error> where
    Self: Sized, [src]

Read and return a value stored for ID k that implements the KeyStoreValue trait for deserialization. If the value is marked as Status::Hidden, an error will be returned.

Returns an error if storing fails.

fn update(
    &self,
    k: &Self::KeyStoreId,
    v: &impl KeyStoreValue
) -> Result<(), Self::Error> where
    Self: Sized, [src]

Update a value stored for ID k with a new value v that implements the KeyStoreValue trait for serialization.

Returns an error if storing fails.

fn delete(&self, k: &Self::KeyStoreId) -> Result<(), Self::Error> where
    Self: Sized, [src]

Delete a value stored for ID k.

Returns an error if storing fails.
