}

A trait that describes a wallet capable of creating a spending Transaction from a set of SpendableOutputDescriptors.

Required Methods

fn spend_spendable_outputs<C: Signing>( &self, descriptors: &[&SpendableOutputDescriptor], outputs: Vec<TxOut>, change_destination_script: ScriptBuf, feerate_sat_per_1000_weight: u32, locktime: Option<LockTime>, secp_ctx: &Secp256k1<C> ) -> Result<Transaction, ()>

Creates a Transaction which spends the given descriptors to the given outputs, plus an output to the given change destination (if sufficient change value remains). The transaction will have a feerate, at least, of the given value.

The locktime argument is used to set the transaction’s locktime. If None, the transaction will have a locktime of 0. It it recommended to set this to the current block height to avoid fee sniping, unless you have some specific reason to use a different locktime.

Returns Err(()) if the output value is greater than the input value minus required fee, if a descriptor was duplicated, or if an output descriptor script_pubkey does not match the one we can spend.

This trait is not object safe.
