Struct WalletSync

pub struct WalletSync<W: Deref + MaybeSync + MaybeSend, L: Deref + MaybeSync + MaybeSend>
where
    W::Target: WalletSourceSync + MaybeSend,
    L::Target: Logger + MaybeSend,
{ /* private fields */ }

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

For an asynchronous version of this wrapper, see Wallet.

Implementations

impl<W: Deref + MaybeSync + MaybeSend, L: Deref + MaybeSync + MaybeSend> WalletSync<W, L>

where W::Target: WalletSourceSync + MaybeSend, L::Target: Logger + MaybeSend,

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

Constructs a new WalletSync instance.

Trait Implementations

impl<W: Deref + MaybeSync + MaybeSend, L: Deref + MaybeSync + MaybeSend> CoinSelectionSourceSync for WalletSync<W, L>

where W::Target: WalletSourceSync + MaybeSend + MaybeSync, L::Target: Logger + MaybeSend + MaybeSync,

fn select_confirmed_utxos( &self, claim_id: ClaimId, must_spend: Vec<Input>, must_pay_to: &[TxOut], target_feerate_sat_per_1000_weight: u32, max_tx_weight: u64, ) -> 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_psbt(&self, psbt: Psbt) -> Result<Transaction, ()>

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