Struct FunctionHandle 

pub struct FunctionHandle(/* private fields */);

Opaque handle for function dispatch.

Replaces FunctionId in the AST to support both built-in and custom functions. Built-in functions use handles with values matching their FunctionId discriminant. Custom functions use handles starting at CUSTOM_HANDLE_BASE.

Implementations

impl FunctionHandle

pub fn is_builtin(&self) -> bool

Check if this handle refers to a built-in function.

pub fn is_custom(&self) -> bool

Check if this handle refers to a custom function.

Trait Implementations

impl Clone for FunctionHandle

fn clone(&self) -> FunctionHandle

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for FunctionHandle

impl Debug for FunctionHandle

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

Formats the value using the given formatter.

impl Eq for FunctionHandle

impl From<FunctionId> for FunctionHandle

fn from(id: FunctionId) -> Self

Converts to this type from the input type.

impl Hash for FunctionHandle

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 FunctionHandle

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