[−][src]Module exonum_merkledb::indexes

All available MerkleDB indexes.

Modules

proof_list	An implementation of a Merkelized version of an array list (Merkle tree).
proof_map	An implementation of a Merkelized version of a map (Merkle Patricia tree).

Entries	Iterator over key-value pairs of an index.
Entry	An index that may only contain one element.
Group	Group of indexes distinguished by a prefix.
KeySetIndex	A set of key items.
Keys	Iterator over keys of an index.
ListIndex	A list of items where elements are added to the end of the list and are removed starting from the end of the list.
MapIndex	A map of keys and values. Access to the elements of this map is obtained using the keys.
ProofEntry	A hashed index that may only contain one element.
SparseListIndex	A list of items similar to `ListIndex`; however, it may contain "spaces". For instance, a list might contain six elements with indexes: `1, 2, 3, 5, 7, 8` (missing 4 and 6). And if you try to get the element for index 4 or 6, you will get `None`.
ValueSetIndex	A set of value items.
Values	Iterator over values of an index.

Database object that supports iteration and continuing iteration from an intermediate position.
