Struct FunctionKey 

pub struct FunctionKey {
    pub name: String,
    pub num_args: i32,
}

Composite lookup key for functions: (UPPERCASE name, num_args).

-1 for num_args means variadic (any number of arguments). Names are stored as uppercase ASCII for case-insensitive matching.

Fields

name: String

Function name, stored as uppercase ASCII.

num_args: i32

Expected argument count, or -1 for variadic.

Implementations

impl FunctionKey

pub fn new(name: &str, num_args: i32) -> Self

Create a new function key with the name canonicalized to uppercase.

Trait Implementations

impl Clone for FunctionKey

fn clone(&self) -> FunctionKey

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FunctionKey

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

Formats the value using the given formatter.

impl Hash for FunctionKey

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for FunctionKey

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