Enum ArgCount 

pub enum ArgCount {
    Exact(usize),
    VarArg(usize),
}

Specifies the expected argument count for a macro.

Variants

Exact(usize)

Exact number of arguments required.

VarArg(usize)

Variable arguments with a minimum count.

Implementations

impl ArgCount

pub fn matches(&self, count: usize) -> bool

Check if the given argument count matches this specification.

pub fn count(&self) -> usize

Get the count value (exact count or minimum for vararg).

pub fn is_vararg(&self) -> bool

Returns true if this is a vararg specification.

Trait Implementations

impl Clone for ArgCount

fn clone(&self) -> ArgCount

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ArgCount

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

Formats the value using the given formatter.

impl PartialEq for ArgCount

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