Crate psbt

PSBT bitcoin library, providing all PSBT functionality from bitcoin library, plus

• constructor, supporting miniscript-based descriptors, input descriptors, all sighash types, spendings from P2C, S2C-tweaked inputs ([construct]);
• advanced signer, supporting pre-segwit, bare and nested segwit v0, taproot key and path spendings, different forms of tweaks & commitments, all sighash types ([sign]);
• commitment-related features: managing tapret-, P2C and S2C-related proprietary keys;
• utility methods for fee computing, lexicographic reordering etc;
• command-line utility for editing PSBT data (WIP).

Re-exports

• pub use p2c::PSBT_IN_P2C_TWEAK;
• pub use p2c::PSBT_P2C_PREFIX;

Modules

• lex_order
  Lexicographic sorting functions.
• p2c
  Processing proprietary PSBT keys related to pay-to-contract (P2C) commitments.
• raw
  Raw PSBT key-value pairs.
• serialize
  PSBT serialization.

Structs

• Input
• Output
• ProprietaryKey
  Proprietary keys (i.e. keys starting with 0xFC byte) with their internal structure according to BIP 174.
• ProprietaryKeyDescriptor
• ProprietaryKeyType
• Psbt
• PsbtSighashType
  A Signature hash type for the corresponding input. As of taproot upgrade, the signature hash type can be either EcdsaSighashType or SchnorrSighashType but it is not possible to know directly which signature hash type the user is dealing with. Therefore, the user is responsible for converting to/from PsbtSighashType from/to the desired signature hash type they need.

Enums
