Trait ValueSelector 

pub trait ValueSelector<S: PlanningSolution, V>: Send + Debug {
    // Required methods
    fn iter_typed<'a, D: Director<S>>(
        &'a self,
        score_director: &'a D,
        descriptor_index: usize,
        entity_index: usize,
    ) -> impl Iterator<Item = V> + 'a;
    fn size<D: Director<S>>(
        &self,
        score_director: &D,
        descriptor_index: usize,
        entity_index: usize,
    ) -> usize;

    // Provided method
    fn is_never_ending(&self) -> bool { ... }
}

A value selector that yields values of type V directly.

Unlike ValueSelector which returns Arc<dyn Any>, this trait returns V inline, eliminating heap allocation per value.

Type Parameters

• S - The planning solution type
• V - The value type

Required Methods

fn iter_typed<'a, D: Director<S>>( &'a self, score_director: &'a D, descriptor_index: usize, entity_index: usize, ) -> impl Iterator<Item = V> + 'a

fn size<D: Director<S>>( &self, score_director: &D, descriptor_index: usize, entity_index: usize, ) -> usize

Provided Methods

fn is_never_ending(&self) -> bool

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
