Data Members

Name	Description
`change_output_size`	Size of a change output in bytes, determined by the output type.
`change_spend_size`	Size of the input to spend a change output in virtual bytes.
`m_avoid_partial_spends`	When true, always spend all (up to OUTPUT_GROUP_MAX_ENTRIES) or none of the outputs associated with the same address. This helps reduce privacy leaks resulting from address reuse. Dust outputs are not eligible to be added to output groups and thus not considered.
`m_change_fee`	Cost of creating the change output.
`m_cost_of_change`	Cost of creating the change output + cost of spending the change output in the future.
`m_discard_feerate`	If the cost to spend a change output at the discard feerate exceeds its value, drop it to fees.
`m_effective_feerate`	The targeted feerate of the transaction being built.
`m_include_unsafe_inputs`	When true, allow unsafe coins to be selected during Coin Selection. This may spend unconfirmed outputs: 1) Received from other wallets, 2) replacing other txs, 3) that have been replaced.
`m_long_term_feerate`	The feerate estimate used to estimate an upper bound on what should be sufficient to spend the change output sometime in the future.
`m_max_tx_weight`	The maximum weight for this transaction.
`m_min_change_target`	Mininmum change to target in Knapsack solver and CoinGrinder: select coins to cover the payment and at least this value of change.
`m_subtract_fee_outputs`	Indicate that we are subtracting the fee from outputs
`m_version`	The version of the transaction we are trying to create.
`min_viable_change`	Minimum amount for creating a change output. If change budget is smaller than min_change then we forgo creation of change output.
`rng_fast`	Randomness to use in the context of coin selection.
`tx_noinputs_size`	Size of the transaction before coin selection, consisting of the header and recipient output(s), excluding the inputs and change output(s).
