Function sp_state_machine::create_proof_check_backend

pub fn create_proof_check_backend<H>(
    root: H::Out,
    proof: StorageProof
) -> Result<TrieBackend<MemoryDB<H>, H>, Box<dyn Error>>where
    H: Hasher,
    H::Out: Codec,

Create a backend used for checking the proof, using H as hasher.

proof and root must match, i.e. root must be the correct root of proof nodes.
