Module transaction

Bitcoin transactions.

A transaction describes a transfer of money. It consumes previously-unspent transaction outputs and produces new ones, satisfying the condition to spend the old outputs (typically a digital signature with a specific key must be provided) and defining the condition to spend the new ones. The use of digital signatures ensures that coins cannot be spent by unauthorized parties.

This module provides the structures and functions needed to support transactions.

Structs

• IndexOutOfBoundsError
  Error attempting to do an out of bounds access on a vector.
• InputWeightPrediction
  Weight prediction of an individual input.
• InputsIndexError
  Error attempting to do an out of bounds access on the transaction inputs vector.
• OutPoint
  A reference to a transaction output.
• OutputsIndexError
  Error attempting to do an out of bounds access on the transaction outputs vector.
• Sequence
  Bitcoin transaction input sequence number.
• Transaction
  Bitcoin transaction.
• TxIn
  Bitcoin transaction input.
• TxOut
  Bitcoin transaction output.
• Txid
  A bitcoin transaction hash/transaction ID.
• Version

Enums

• ParseOutPointError
  An error in parsing an OutPoint.
• TxVerifyErrorbitcoinconsensus

Functions

• effective_value
  Computes the value of an output accounting for the cost of spending it.
• predict_weight
  Predicts the weight of a to-be-constructed transaction.
• predict_weight_from_slices
