Struct ComputedValueRangeProvider 

pub struct ComputedValueRangeProvider<S, V, F>
where
    F: Fn(&S) -> Vec<V> + Send + Sync,
{ /* private fields */ }

A value range provider that computes values dynamically.

Use this when values are computed from solution state rather than stored in a field.

Implementations

impl<S, V, F> ComputedValueRangeProvider<S, V, F>

where F: Fn(&S) -> Vec<V> + Send + Sync,

pub fn new(compute: F) -> Self

Creates a new computed value range provider.

Trait Implementations

impl<S, V, F> ValueRangeProvider<S, V> for ComputedValueRangeProvider<S, V, F>

where S: Send + Sync, V: Send + Sync, F: Fn(&S) -> Vec<V> + Send + Sync,

fn get_values(&self, solution: &S) -> Vec<V>

Returns all possible values for the variable.

fn value_count(&self, solution: &S) -> usize

Returns the number of possible values.

fn is_empty(&self, solution: &S) -> bool

Returns whether the value range is empty.
