Expand description

A reference to a transaction output.

Bitcoin Core References

Fields§

§txid: Txid

The referenced transaction’s txid.

§vout: u32

The index of the referenced output in its transaction’s vout.

Implementations§

source§

impl OutPoint

source

pub fn new(txid: Txid, vout: u32) -> OutPoint

Creates a new OutPoint.

source

pub fn null() -> OutPoint

Creates a “null” OutPoint.

This value is used for coinbase transactions because they don’t have any previous outputs.

source

pub fn is_null(&self) -> bool

Checks if an OutPoint is “null”.

Examples
use bitcoin::constants::genesis_block;
use bitcoin::Network;

let block = genesis_block(Network::Bitcoin);
let tx = &block.txdata[0];

// Coinbase transactions don't have any previous output.
assert!(tx.input[0].previous_output.is_null());
