Enum FunctionArity 

pub enum FunctionArity {
    Exact(usize),
    Range(usize, usize),
    Variadic,
    VariadicMin(usize),
}

Expected function arity.

Variants

Exact(usize)

Exact number of arguments.

Range(usize, usize)

Range of acceptable argument counts.

Variadic

Any number of arguments.

VariadicMin(usize)

Minimum number of arguments.

Trait Implementations

impl Clone for FunctionArity

fn clone(&self) -> FunctionArity

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FunctionArity

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

Formats the value using the given formatter.

impl PartialEq for FunctionArity

fn eq(&self, other: &FunctionArity) -> 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.
