Expand description

An extension trait for Wallet.

Provided Methods§

Source

fn peek_next_address(&self) -> AddressInfo

Peek into the next address.

Source

fn unconfirmed_txids(&self) -> impl Iterator<Item = Txid>

Returns an iterator for each unconfirmed transaction in the wallet.

Source

fn unconfirmed_txs(&self) -> impl Iterator<Item = Arc<Transaction>>

Returns an iterator for each unconfirmed transaction in the wallet, useful for syncing with bitcoin core.

Source

fn is_trusted_utxo(&self, outpoint: OutPoint, min_confs: u32) -> bool

Check whether a UTXO can be trusted for spending.

Delegates to WalletExt::is_trusted_tx on the creating transaction.

Source

fn is_trusted_tx(&self, txid: Txid, min_confs: u32) -> bool

Check whether a transaction can be trusted to confirm on chain.

A transaction is trusted if:

min_confs is 0 (unconditionally trusted), or
it has at least min_confs confirmations, or
all its inputs are ours and their creating transactions are also trusted (checked recursively).

To keep the check cheap, at most 100 ancestor transactions are visited. If the budget is exhausted the transaction is considered untrusted.
