Expand description
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
sourceimpl OutPoint
impl OutPoint
sourcepub fn null() -> OutPoint
pub fn null() -> OutPoint
Creates a “null” OutPoint
.
This value is used for coinbase transactions because they don’t have any previous outputs.
sourcepub fn is_null(&self) -> bool
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!(tx.input[0].previous_output.is_null());
