[−][src]Module exonum_merkledb::indexes::proof_map

An implementation of a Merkelized version of a map (Merkle Patricia tree).

Structs

CheckedMapProof	Version of `MapProof` obtained after verification.
Hashed	Hashed variant of a key, representing the transform via SHA-256 hash function.
MapProof	View of a `ProofMapIndex`, i.e., a subset of its elements coupled with a proof, which jointly allow restoring the `object_hash()` of the index. Apart from the existing elements, `MapProof` can assert absence of certain keys from the underlying index.
ProofMapIndex	A Merkelized version of a map that provides proofs of existence or non-existence for the map keys.
Raw	Raw variant of a key, representing the identity transform.

MapProofError	An error returned when a map proof is invalid.
ValidationError	Errors that can occur while validating a `ListProof` or `MapProof` against a trusted collection hash.

PROOF_MAP_KEY_SIZE	Size in bytes of the `Hash`.
PROOF_PATH_SIZE	Size in bytes of the `ProofPath`.

RawKey	Trait signalling that a key is usable as a key of `RawProofMapIndex`.
ToProofPath	Trait defining key transformation into the format usable in Merkle Patricia trees.

Raw variant of the ProofMapIndex, useful for keys that mapped directly to ProofPath without hashing. For example Hash and PublicKey.
