Modules

• evaluator - the core [Evaluator] struct and expression evaluation
• values - the [Value] enum representing all runtime values
• native - [Module], [NativeFn], and the trait system for binding Rust functions
• scopes - environment stack: push/pop/insert/assign/get
• stdlib - all built-in stdlib modules
• utils - binary/unary operator dispatch and statement evaluation

Modules

evaluator

Core evaluator - expression evaluation, function calls, and the runtime state.

evaluator_types 🔒

Extra expression evaluation helpers that live outside the main evaluator.rs to keep it from becoming too large.

native

The native function binding system - Module, NativeFn, and the IntoNativeFn / FromValue / IntoValue trait machinery.

scopes 🔒

Environment stack operations - scope management and slot-indexed value access.

stdlib

The rl standard library - all built-in modules registered under std::*.

utils 🔒

Internal evaluator utilities - binary/unary operator dispatch and statement evaluation.

values

Runtime value types for the rl interpreter.
