Trait sudoku_variants::constraint::CloneConstraint[−][src]

pub trait CloneConstraint: Constraint {
    fn clone_box(&self) -> Box<dyn CloneConstraint>;
}

A trait for cloneable Constraints which is used in the DynamicConstraint to clone trait objects. Normally a user should not have to implement this trait manually, as it is automatically implemented for all Constraints that implement Clone (and have static lifetime).

Required methods

fn clone_box(&self) -> Box<dyn CloneConstraint>[src]
