Struct Registry 

pub struct Registry { /* private fields */ }

The runtime registry of built-in and user-registered spreadsheet functions.

Implementations

impl Registry

pub fn new() -> Self

pub fn register_eager(&mut self, name: &str, f: EagerFn, meta: FunctionMeta)

Register a user-facing eager function with metadata. Appears in list_functions().

pub fn register_lazy(&mut self, name: &str, f: LazyFn, meta: FunctionMeta)

Register a user-facing lazy function with metadata. Appears in list_functions().

pub fn register_internal(&mut self, name: &str, f: EagerFn)

Register an internal/compiler-only eager function without metadata. Never appears in list_functions().

pub fn register_internal_lazy(&mut self, name: &str, f: LazyFn)

Register an internal/compiler-only lazy function without metadata. Never appears in list_functions().

pub fn get(&self, name: &str) -> Option<&FunctionKind>

pub fn list_functions(&self) -> impl Iterator<Item = (&str, &FunctionMeta)>

Iterate all user-facing functions with their metadata. The registry is the single source of truth — this can never drift.
