Struct bdk_chain::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 const 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::consensus::params;
use bitcoin::constants::genesis_block;
use bitcoin::Network;

let block = genesis_block(&params::MAINNET);
let tx = &block.txdata[0];

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

fn deserialize<D>( deserializer: D ) -> Result<OutPoint, <D as Deserializer<'de>>::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl Encodable for OutPoint

fn consensus_encode<W>(&self, w: &mut W) -> Result<usize, Error>

where W: Write + ?Sized,

Encodes an object with a well-defined format.

impl FromStr for OutPoint

type Err = ParseOutPointError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<OutPoint, <OutPoint as FromStr>::Err>

Parses a string s to return a value of this type.

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,

impl PartialEq for OutPoint

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

This method tests for self and other values to be equal, and is used by ==.

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

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

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

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

This method tests greater than (for self and other) and is used by the > operator.

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

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