Structs

• AuthDigest
  An authorizing data commitment hash as specified in ZIP-244.
• Hash
  A transaction ID, which uniquely identifies mined v5 transactions, and all v1-v4 transactions.
• HashType
  The different SigHash types, as defined in https://zips.z.cash/zip-0143
• JoinSplitData
  A bundle of JoinSplit descriptions and signature data.
• Memo
  A 512-byte (plaintext) memo associated with a note, as described in protocol specification §5.5.
• SerializedTransaction
  A serialized transaction.
• SigHash
  A Signature Hash (or SIGHASH) as specified in https://zips.z.cash/protocol/protocol.pdf#sighash
• SigHasher
  A SigHasher context which stores precomputed data that is reused between sighash computations for the same transaction.
• UnminedTx
  An unmined transaction, and its pre-calculated unique identifying ID.
• VerifiedUnminedTx
  A verified unmined transaction, and the corresponding transaction fee.
• WtxId
  A witnessed transaction ID, which uniquely identifies unmined v5 transactions.

Enums

• LockTime
  A Bitcoin-style locktime, representing either a block height or an epoch time.
• Transaction
  A Zcash transaction.
• UnminedTxId
  A unique identifier for an unmined transaction, regardless of version.

Constants
