Required Methods

fn get_with_proof( &self, key: StorageKey, witness: &Self::Witness ) -> StorageProof<Self::Proof>

Returns the value corresponding to the key or None if key is absent and a proof to get the value. Panics if get_with_proof_from_state_map returns None in place of the proof.

Provided Methods

fn get_with_proof_from_state_map<Q, K, V, Codec>( &self, key: &Q, state_map: &StateMap<K, V, Codec>, witness: &Self::Witness ) -> StorageProof<Self::Proof>where Codec: EncodeKeyLike<Q, K>,
