Struct breez_sdk_core::bitcoin::OutPoint

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

A reference to a transaction output.

• COutPoint definition

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

Creates 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!(tx.input[0].previous_output.is_null());

impl Hash for OutPoint

fn hash<__H>(&self, state: &mut __H)

where __H: Hasher,

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Ord for OutPoint

fn cmp(&self, other: &OutPoint) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized + PartialOrd,

Restrict a value to a certain interval.

impl PartialEq for OutPoint

fn eq(&self, other: &OutPoint) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.

fn encode(&self) -> Vec<u8>

Writes self out to a Vec<u8>.

fn serialized_length(&self) -> usize

Gets the length of this object after it has been serialized. This can be overridden to optimize cases where we prepend an object with its length.
