Required methods

fn new(methods: Vec<Self::Method>) -> Self[src]

Constructs a new constraint with the provided methods.

fn name(&self) -> &str[src]

Returns a reference to the name of the constraint.

fn methods(&self) -> &[Self::Method][src]

Returns a slice to the methods of the constraint.

fn add_method(&mut self, m: Self::Method)[src]

Adds a new method to the constraint.

fn remove_method(&mut self, name: &str)[src]

Removes a method from the constraint.

fn variables(&self) -> &[usize][src]

Returns a slice to the variables used by the methods of the constraint.

fn is_active(&self) -> bool[src]

Whether or not this constraint is active.
