Struct Module 

pub struct Module {
    pub name: String,
    pub functions: HashMap<String, NativeFn>,
    pub submodules: HashMap<String, Module>,
}

A named collection of NativeFns, optionally containing sub-Modules.

Fields

name: String

The module name as used in import paths (e.g. "io", "math").

functions: HashMap<String, NativeFn>

Named functions registered in this module.

submodules: HashMap<String, Module>

Named submodules (e.g. math::consts).

Implementations

impl Module

pub fn new(name: impl Into<String>) -> Self

pub fn with_function<F, A>(self, name: impl Into<String>, f: F) -> Self

where F: IntoNativeFn<A>,

Registers a typed Rust function using the IntoNativeFn trait.

pub fn with_raw_function<F>(self, name: impl Into<String>, f: F) -> Self

where F: Fn(&mut Evaluator, Vec<Value>, Span) -> Result<Value, Error> + Send + Sync + 'static,

Registers a raw fn(&mut Evaluator, Vec<Value>, Span) -> Result<Value, Error> directly, bypassing the IntoNativeFn machinery (used for variadic functions like print).

pub fn with_module(self, m: Module) -> Self

Registers a submodule.

pub fn resolve(&self, path: &[String]) -> Option<&NativeFn>

Walks the module tree along path, returning the NativeFn at the leaf, or None if any segment is missing.
