Enums

• IndexError
  An error occurred when verifying the tree’s index.
• WitnessError
  An error occurred when verifying the tree’s contained witnesses.

Functions

• all_proofs

• cached_hashes
  Verify that every internally cached hash matches what it should be, by re-hashing all of them.
• forgotten
  Verify that the internal forgotten versions are consistent throughout the tree.
• index
