Struct OrderedUtxo

pub struct OrderedUtxo {
    pub utxo: Utxo,
    pub tx_index_in_block: usize,
}

A Utxo, and the index of its transaction within its block.

This extra index is used to check that spends come after outputs, when a new output and its spend are both in the same block.

The extra index is only used during block verification, so it does not need to be sent to the state.

Fields

utxo: Utxo

An unspent transaction output.

tx_index_in_block: usize

The index of the transaction that created the output, in the block at height.

Used to make sure that transaction can only spend outputs that were created earlier in the chain.

Note: this is different from OutPoint.index, which is the index of the output in its transaction.

Implementations

impl OrderedUtxo

pub fn new( output: Output, height: Height, tx_index_in_block: usize, ) -> OrderedUtxo

Create a new ordered UTXO from its fields.

pub fn from_utxo(utxo: Utxo, tx_index_in_block: usize) -> OrderedUtxo

Create a new ordered UTXO from a UTXO and transaction index.

Trait Implementations

impl Arbitrary for OrderedUtxo

type Parameters = (<Utxo as Arbitrary>::Parameters, <usize as Arbitrary>::Parameters)

The type of parameters that arbitrary_with accepts for configuration of the generated Strategy. Parameters must implement Default.

type Strategy = Map<(<Utxo as Arbitrary>::Strategy, <usize as Arbitrary>::Strategy), fn(_: (Utxo, usize)) -> OrderedUtxo>

The type of Strategy used to generate values of type Self.

fn arbitrary_with(_top: Self::Parameters) -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self). The strategy is passed the arguments given in args.

fn arbitrary() -> Self::Strategy

Generates a Strategy for producing arbitrary values of type the implementing type (Self).

impl AsRef<Utxo> for OrderedUtxo

fn as_ref(&self) -> &Utxo

Converts this type into a shared reference of the (usually inferred) input type.

impl Clone for OrderedUtxo

fn clone(&self) -> OrderedUtxo

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for OrderedUtxo

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

Formats the value using the given formatter.

impl PartialEq for OrderedUtxo

fn eq(&self, other: &OrderedUtxo) -> 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.
