Struct FunctionTable 

pub struct FunctionTable { /* private fields */ }

The global function table.

Maps function indices to their entries. Built during compilation and used at runtime for function dispatch.

Implementations

impl FunctionTable

pub fn new() -> Self

Create a new empty function table.

pub fn with_capacity(cap: usize) -> Self

Create with pre-allocated capacity.

pub fn register(&mut self, entry: FunctionEntry) -> FnPtr

Register a new function and return its pointer.

pub fn get(&self, ptr: FnPtr) -> Option<&FunctionEntry>

Look up a function entry by pointer.

pub fn get_by_name(&self, name: &str) -> Option<(FnPtr, &FunctionEntry)>

Look up a function entry by name.

pub fn len(&self) -> usize

Number of registered functions.

pub fn is_empty(&self) -> bool

Check if the table is empty.

pub fn iter(&self) -> impl Iterator<Item = (FnPtr, &FunctionEntry)>

Iterate over all entries.

pub fn register_builtins(&mut self)

Register built-in functions.
