Struct SplitPolicy

Source
pub struct SplitPolicy { /* private fields */ }
Expand description

A policy that describes how change output should be split into multiple notes for the purpose of note management.

If an account contains at least Self::target_output_count notes having at least value Self::min_split_output_value, this policy will recommend a single output; if the account contains fewer such notes, this policy will recommend that multiple outputs be produced in order to achieve the target.

Implementations§

Source§

impl SplitPolicy

Source

pub fn with_min_output_value( target_output_count: NonZeroUsize, min_split_output_value: Zatoshis, ) -> Self

Constructs a new SplitPolicy that splits change to ensure the given number of spendable outputs exists within an account, each having at least the specified minimum note value.

Source

pub fn single_output() -> Self

Constructs a SplitPolicy that prescribes a single output (no splitting).

Source

pub fn target_output_count(&self) -> NonZeroUsize

Returns the number of outputs that this policy will attempt to ensure that the wallet has available for spending.

Source

pub fn min_split_output_value(&self) -> Option<Zatoshis>

Returns the minimum value for a note resulting from splitting of change.

Source

pub fn split_count( &self, existing_notes: Option<usize>, existing_notes_total: Option<Zatoshis>, total_change: Zatoshis, ) -> NonZeroUsize

Returns the number of output notes to produce from the given total change value, given the total value and number of existing unspent notes in the account and this policy.

If splitting change to produce Self::target_output_count would result in notes of value less than Self::min_split_output_value, then this will suggest a smaller number of splits so that each resulting change note has sufficient value.
