Module zip317

Change strategies designed to implement the ZIP 317 fee rules.

Change selection in ZIP 317 requires careful handling of low-valued inputs to ensure that inputs added to a transaction do not cause fees to rise by an amount greater than their value.

Structs

MultiOutputChangeStrategy

A change strategy that attempts to split the change value into some number of equal-sized notes as dictated by the included SplitPolicy value.

SingleOutputChangeStrategy

A change strategy that proposes change as a single output. The output pool is chosen as the most current pool that avoids unnecessary pool-crossing (with a specified fallback when the transaction has no shielded inputs). Fee calculation is delegated to the provided fee rule.

Traits
