Struct 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 monacoin::blockdata::constants::genesis_block;
use monacoin::network::constants::Network;

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

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

Trait Implementations

impl Clone for OutPoint

fn clone(&self) -> OutPoint

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for OutPoint

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

Formats the value using the given formatter.

impl Decodable for OutPoint

fn consensus_decode<D: Read>(d: D) -> Result<Self, Error>

Decode an object with a well-defined format

impl Default for OutPoint

fn default() -> Self

Returns the “default value” for a type.

impl Display for OutPoint

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

Formats the value using the given formatter.

impl Encodable for OutPoint

fn consensus_encode<S: Write>(&self, s: S) -> Result<usize, Error>

Encode an object with a well-defined format, should only ever error if the underlying Write errors. Returns the number of bytes written on success

impl FromStr for OutPoint

type Err = ParseOutPointError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

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

impl Hash for OutPoint

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

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,

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.

impl PartialOrd for OutPoint

fn partial_cmp(&self, other: &OutPoint) -> Option<Ordering>

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.

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

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.
