Module bdk_chain::bitcoin::psbt

Partially Signed Bitcoin Transactions.

Implementation of BIP174 Partially Signed Bitcoin Transaction Format as defined at https://github.com/bitcoin/bips/blob/master/bip-0174.mediawiki except we define PSBTs containing non-standard sighash types as invalid.

Modules

• raw
  Raw PSBT key-value pairs.
• serialize
  PSBT serialization.

Structs

• Input
  A key-value map for an input of the corresponding index in the unsigned transaction.
• Output
  A key-value map for an output of the corresponding index in the unsigned transaction.
• Psbt
  A Partially Signed Transaction.
• PsbtSighashType
  A Signature hash type for the corresponding input.

Enums

• Error
  Ways that a Partially Signed Transaction might fail.
• ExtractTxError
  This error is returned when extracting a Transaction from a Psbt.
• GetKeyError
  Errors when getting a key.
• IndexOutOfBoundsError
  Input index out of bounds (actual index, maximum index allowed).
• KeyRequest
  Data required to call GetKey to get the private key to sign an input.
• OutputType
  The various output types supported by the Bitcoin network.
• PsbtParseError
  Error encountered during PSBT decoding from Base64 string.
• SignError
  Errors encountered while calculating the sighash message.
• SigningAlgorithm
  Signing algorithms supported by the Bitcoin network.
• SigningKeys
  A list of keys used to sign an input.

Traits

• GetKey
  Trait to get a private key from a key request, key is then used to sign an input.

Type Aliases

• SigningErrors
  Map of input index -> the error encountered while attempting to sign that input.
• SigningKeysMap
  Map of input index -> signing key for that input (see SigningKeys).
