Struct AssignmentPolicy 

pub struct AssignmentPolicy<C> {
    pub insertion_costs: Vec<C>,
    pub deletion_costs: Vec<C>,
    pub doubling: DoublingPolicy<C>,
    pub voice_crossing: VoiceCrossingPolicy,
}

Costs and structural rules for one assignment.

Fields

insertion_costs: Vec<C>

Cost for each target that enters without a source.

deletion_costs: Vec<C>

Cost for each source that leaves without a target.

doubling: DoublingPolicy<C>

Whether and at what cost sources may be doubled.

voice_crossing: VoiceCrossingPolicy

Whether source voices may cross.

Implementations

impl<C> AssignmentPolicy<C>

pub fn new(insertion_costs: Vec<C>, deletion_costs: Vec<C>) -> Self

Builds a policy with explicit insertion/deletion costs, no doubling, and crossings allowed.

pub fn with_doubling(self, per_source: Vec<C>) -> Self

Enables source doubling at a per-source incremental cost.

pub fn with_voice_crossing(self, policy: VoiceCrossingPolicy) -> Self

Sets the voice-crossing policy.
