Struct breez_sdk_core::lightning::events::bump_transaction::Wallet

pub struct Wallet<W, L>
where
    W: Deref,
    L: Deref,
    <W as Deref>::Target: WalletSource,
    <L as Deref>::Target: Logger,
{ /* private fields */ }

A wrapper over WalletSource that implements CoinSelection by preferring UTXOs that would avoid conflicting double spends. If not enough UTXOs are available to do so, conflicting double spends may happen.

Implementations

impl<W, L> Wallet<W, L>

where W: Deref, L: Deref, <W as Deref>::Target: WalletSource, <L as Deref>::Target: Logger,

pub fn new(source: W, logger: L) -> Wallet<W, L>

Returns a new instance backed by the given WalletSource that serves as an implementation of CoinSelectionSource.

Trait Implementations

impl<W, L> CoinSelectionSource for Wallet<W, L>

where W: Deref, L: Deref, <W as Deref>::Target: WalletSource, <L as Deref>::Target: Logger,

fn select_confirmed_utxos( &self, claim_id: ClaimId, must_spend: Vec<Input>, must_pay_to: &[TxOut], target_feerate_sat_per_1000_weight: u32, ) -> Result<CoinSelection, ()>

Performs coin selection of a set of UTXOs, with at least 1 confirmation each, that are available to spend. Implementations are free to pick their coin selection algorithm of choice, as long as the following requirements are met:

fn sign_tx(&self, tx: Transaction) -> Result<Transaction, ()>

Signs and provides the full witness for all inputs within the transaction known to the trait (i.e., any provided via CoinSelectionSource::select_confirmed_utxos).
