Struct Module 

pub struct Module {
    pub name: String,
    pub code: Vec<Instruction>,
    pub functions: HashMap<(String, u8), FunctionDef>,
    pub exports: HashSet<(String, u8)>,
}

A compiled module containing functions.

Fields

name: String

Module name (e.g., “math”, “lists”).

code: Vec<Instruction>

All bytecode for this module, concatenated. Functions reference ranges within this code.

functions: HashMap<(String, u8), FunctionDef>

Function table: maps (name, arity) -> function metadata.

exports: HashSet<(String, u8)>

Exported functions (subset of functions callable from outside).

Implementations

impl Module

pub fn new(name: String) -> Self

Create a new empty module.

pub fn add_function(&mut self, name: String, arity: u8, code: Vec<Instruction>)

Add a function to this module.

The function’s code is appended to the module’s code vector, and a FunctionDef is created pointing to the entry point.

pub fn add_function_at(&mut self, name: String, arity: u8, entry: usize)

Add a function definition at a specific entry point.

Used by codegen when code is built separately.

pub fn export(&mut self, name: &str, arity: u8)

Mark a function as exported (callable from other modules).

pub fn get_function(&self, name: &str, arity: u8) -> Option<&FunctionDef>

Look up a function by name and arity.

pub fn is_exported(&self, name: &str, arity: u8) -> bool

Check if a function is exported.

Trait Implementations

impl Clone for Module

fn clone(&self) -> Module

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Module

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

Formats the value using the given formatter.
