pub trait PsbtUtils {
    fn get_utxo_for(&self, input_index: usize) -> Option<TxOut>;

Expand description

Required Methods§

Get the TxOut for the specified input index, if it doesn’t exist in the PSBT None is returned.

The total transaction fee amount, sum of input amounts minus sum of output amounts, in sats. If the PSBT is missing a TxOut for an input returns None.
