Module bump_transaction

Utilities for bumping transactions originating from Events.

Structs

• AnchorDescriptor
  A descriptor used to sign for a commitment transaction’s anchor output.
• BumpTransactionEventHandler
  A handler for Event::BumpTransaction events that sources confirmed UTXOs from a CoinSelectionSource to fee bump transactions via Child-Pays-For-Parent (CPFP) or Replace-By-Fee (RBF).
• CoinSelection
  The result of a successful coin selection attempt for a transaction requiring additional UTXOs to cover its fees.
• Input
  An input that must be included in a transaction when performing coin selection through CoinSelectionSource::select_confirmed_utxos. It is guaranteed to be a SegWit input, so it must have an empty TxIn::script_sig when spent.
• Utxo
  An unspent transaction output that is available to spend resulting from a successful CoinSelection attempt.
• Wallet
  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.

Enums

• BumpTransactionEvent
  Represents the different types of transactions, originating from LDK, to be bumped.

Traits

• CoinSelectionSource
  An abstraction over a bitcoin wallet that can perform coin selection over a set of UTXOs and can sign for them. The coin selection method aims to mimic Bitcoin Core’s fundrawtransaction RPC, which most wallets should be able to satisfy. Otherwise, consider implementing WalletSource, which can provide a default implementation of this trait when used with Wallet.
• WalletSource
  An alternative to CoinSelectionSource that can be implemented and used along Wallet to provide a default implementation to CoinSelectionSource.
