Enum Arity 

pub enum Arity {
    Fixed(usize),
    Variable,
}

Represents the arity (number of arguments) of a function signature

Variants

Fixed(usize)

Fixed number of arguments

Variable

Variable number of arguments (e.g., Variadic, VariadicAny, UserDefined)

Trait Implementations

impl Clone for Arity

fn clone(&self) -> Arity

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Arity

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Arity

fn eq(&self, other: &Arity) -> bool

Tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
