|---|---|
| rng_fast | Randomness source to use during coin selection. |
| change_output_size | Size of a change output in bytes. |
| change_spend_size | Size of the input spending a change output in virtual bytes. |
| min_change_target | Minimum change to target in the Knapsack solver and CoinGrinder. |
| effective_feerate | Targeted feerate of the transaction being built. |
| long_term_feerate | Feerate estimate for spending the change output in the future. |
| discard_feerate | Feerate below which spending a change output is not worthwhile. |
| tx_noinputs_size | Size of the transaction before inputs and change are added. |
| avoid_partial | Whether to spend all or none of the outputs sharing an address. |
| max_tx_weight | Optional maximum weight for the transaction. |
