Module instruction

Utility functions to simplify the handling of ZK ElGamal proof program instruction data in SPL crates

Enums

• ProofData
  A proof data type to distinguish between proof data included as part of zk-token proof instruction data and proof data stored in a record account.
• ProofLocation
  A proof location type meant to be used for arguments to instruction constructors.

Functions

• check_zk_elgamal_proof_program_account
  Checks that the supplied program ID is correct for the ZK ElGamal proof program
• decode_proof_instruction_context
  Decodes the proof context data associated with a zero-knowledge proof instruction.
• process_proof_location
  Processes a proof location for instruction creation. Adds relevant accounts to supplied account vector
• verify_and_extract_context
  Verify zero-knowledge proof and return the corresponding proof context.
• zk_proof_type_to_instruction
  Converts a zk proof type to a corresponding ZK ElGamal proof program instruction that verifies the proof.
