Implementations on Foreign Types
impl Arity for usize[src]
impl Arity for (usize, usize)[src]
Closed interval arity.
This type represents a closed interval arity with a minimum and maximum inclusive range.
impl Arity for (usize, Option<usize>)[src]
Open interval arity.
This type represents an open interval arity with a minimum and optional
maximum inclusive range. When there is no maximum (
None), the maximum
arity is unspecified. This typically means that there is no theoretical
