Trait ConstructionForager 

pub trait ConstructionForager<S, M>: Send + Debug
where
    S: PlanningSolution,
    M: Move<S>,
{
    // Required method
    fn pick_move_index<D: Director<S>>(
        &self,
        placement: &Placement<S, M>,
        score_director: &mut D,
    ) -> Option<usize>;
}

Trait for selecting a move during construction.

Foragers evaluate candidate moves and pick one based on their strategy. Returns the index of the selected move, not a cloned move.

Type Parameters

• S - The planning solution type
• M - The move type

Required Methods

fn pick_move_index<D: Director<S>>( &self, placement: &Placement<S, M>, score_director: &mut D, ) -> Option<usize>

Picks a move index from the placement’s candidates.

Returns None if no suitable move is found.

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.
