Defines how jobs are moved in solution context. Index of original affected route context is passed.

Required Methods

fn remove_from_required( &self, solution_ctx: &SolutionContext, route_index: Option<usize>, job: &Job ) -> bool

Returns true if job is moved from required to ignored.

fn promote_to_required( &self, solution_ctx: &SolutionContext, route_index: Option<usize>, job: &Job ) -> bool

Returns true if job is moved from ignored to required.

fn remove_from_locked( &self, solution_ctx: &SolutionContext, route_index: Option<usize>, job: &Job ) -> bool

Returns true if job is removed from locked.

fn promote_to_locked( &self, solution_ctx: &SolutionContext, route_index: Option<usize>, job: &Job ) -> bool

Returns true if job is moved to locked.
