Structs

• Annex
  The Annex struct enforces first byte to be 0x50.
• Bip340Sig
• BlockHash
• BlockHeader
• BlockMerkleRoot
• ByteStr
• CompressedPk
• ControlBlock
• FutureLeafVer
  Inner type representing future (non-tapscript) leaf versions. See LeafVer::Future.
• InternalKeypair
  Internal taproot public key, which can be present only in key fragment inside taproot descriptors.
• InternalPk
  Internal taproot public key, which can be present only in key fragment inside taproot descriptors.
• InvalidLeafVer
  invalid taproot leaf version {0}.
• InvalidParityValue
  invalid parity value {0} - must be 0 or 1
• InvalidTimelock
  Error constructing timelock from the provided value.
• LeafScript
• LegacyPk
• LegacySig
• LockHeight
  Value for a transaction nTimeLock field which is guaranteed to represent a block height number which is always less than 500000000.
• LockTime
• LockTimestamp
  Value for a transaction nTimeLock field which is guaranteed to represent a UNIX timestamp which is always either 0 or a greater than or equal to 500000000.
• NonStandardValue
  the provided value {value} for {matter} is non-standard; while it is accepted by the bitcoin consensus rules, the software prohibits from using it.
• Outpoint
• OutputPk
  Output taproot key - an InternalPk tweaked with merkle root of the script tree - or its own hash. Used only inside addresses and raw taproot descriptors.
• PrevoutMismatch
• PubkeyHash
• RedeemScript
• Sats
• ScriptBytes
• ScriptCode
  Type used for generating sighash in SegWit signing
• ScriptHash
• ScriptPubkey
• SeqNo
• SigScript
• Sighash
• SighashCache
  Efficiently calculates signature hash message for legacy, segwit and taproot inputs.
• SighashType
• TapBranchHash
• TapLeafHash
• TapMerklePath
• TapNodeHash
• TapScript
• TapSighash
• Tx
• TxIn
• TxOut
• TxVer
• Txid
• UncompressedPk
• VBytes
• VarInt
  A variable-length unsigned integer.
• Vout
• WPubkeyHash
• WScriptHash
• WeightUnits
• Witness
• WitnessProgram
  Witness program as defined in BIP141.
• WitnessScript
• Wtxid
• XOnlyPk
  Generic taproot x-only (BIP-340) public key - a wrapper around XOnlyPublicKey providing APIs compatible with the rest of the library. Should be used everywhere when InternalPk and OutputPk do not apply: as an output of BIP32 key derivation functions, inside tapscripts/ leafscripts etc.

Constants

• LIB_NAME_BITCOIN

  The SHA-256 midstate value for the TapSig hash.
• SEQ_NO_CSV_DISABLE_MASK
• SEQ_NO_CSV_TYPE_MASK
• TAPROOT_ANNEX_PREFIX
  Taproot annex prefix.
• TAPROOT_LEAF_MASK
  Tapleaf mask for getting the leaf version from first byte of control block.
• TAPROOT_LEAF_TAPSCRIPT
  Tapscript leaf version.

Traits

• ConsensusDecode
• ConsensusEncode
• IntoTapHash
• LenVarInt
• Weight

Type Aliases

• VarIntArray
  Bitcoin consensus allows arrays which length is encoded as VarInt to grow up to 64-bit values. However, at the same time no consensus rule allows any block data structure to exceed 2^32 bytes (4GB), and any change to that rule will be a hardfork. So for practical reasons we are safe to restrict the maximum size here with just 32 bits.
