@midnight/ledger / UtxoState

Class: UtxoState

The sub-state for unshielded UTXOs

Constructors​

Constructor​

new UtxoState(): UtxoState;

Returns​

UtxoState

Properties​

utxos​

readonly utxos: Set<Utxo>;

The set of valid UTXOs

Methods​

delta()​

delta(prior, filterBy?): [Set<Utxo>, Set<Utxo>];

Given a prior UTXO state, produce the set differences this \ prior, and prior \ this, optionally filtered by a further condition.

Note that this should be more efficient than iterating or manifesting the utxos value, as the low-level implementation can avoid traversing shared sub-structures.

Parameters​

prior​

UtxoState

filterBy?​

(utxo) => boolean

Returns​

[Set<Utxo>, Set<Utxo>]

filter()​

filter(addr): Set<Utxo>;

Filters out the UTXOs owned by a specific user address

Parameters​

addr​

string

Returns​

Set<Utxo>

lookupMeta()​

lookupMeta(utxo): undefined | UtxoMeta;

Lookup the metadata for a specific UTXO.

Parameters​

utxo​

Utxo

Returns​

undefined | UtxoMeta

new()​

static new(utxos): UtxoState;

Parameters​

utxos​

Map<Utxo, UtxoMeta>

Returns​

UtxoState
