TransactionOutPoint

A reference to a specific output of a previous transaction — a (txid, output-index) pair used by TransactionInput to identify the UTXO being spent.

final class TransactionOutPoint

Overview

Outpoints are obtained from a TransactionInput via outPoint; there is no public create initializer.

The coinbase-transaction sentinel is txid == all-zeros and index == 0xFFFFFFFF — no previous transaction is being referenced.

Wraps the opaque btck_TransactionOutPoint type; deinit calls btck_transaction_out_point_destroy when the last Swift reference drops.

Instance Properties

var index: UInt32
The zero-based index of the output in the referenced transaction. 0xFFFFFFFF is the coinbase sentinel.
var txid: Txid
The TXID of the referenced transaction as an owned copy. For coinbase outpoints, all 32 bytes are zero.
