Struct bitcoin::blockdata::transaction::OutPoint

pub struct OutPoint {
    pub txid: Txid,
    pub vout: u32,
}

A reference to a transaction output

Fields

txid: Txid

The referenced transaction’s txid

vout: u32

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

Implementations

impl OutPoint

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

Create a new OutPoint.

pub fn null() -> OutPoint

Creates a “null” OutPoint.

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

pub fn is_null(&self) -> bool

Checks if an OutPoint is “null”.

Examples

use bitcoin::blockdata::constants::genesis_block;
use bitcoin::network::constants::Network;

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

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