Type of an index supported by Exonum.

IndexType is used for type checking indexes when they are created/accessed.

Variants

Map

Non-merkelized map index.

List

Non-merkelized list index.

Entry

Single entry acting like a Rust Option.

ValueSet

Set index with elements stored in a hash table.

KeySet

Set index with elements stored as keys in the underlying KV storage.

SparseList

Sparse list index.

ProofList

Merkelized list index.

ProofMap

Merkelized map index.

ProofEntry

Merkelized entry.

Tombstone

Tombstone indicating necessity to remove an index after migration is completed.

Methods
