Struct ModuleRegistry 

pub struct ModuleRegistry { /* private fields */ }

Process-global module registry. Holds every module that’s been loaded so far, keyed by path. Two (require "lib/auth") calls from different sites share one Module instance — the file is loaded + evaluated exactly once.

Implementations

impl ModuleRegistry

pub fn new() -> Self

pub fn has(&self, path: &str) -> bool

Has this path already been fully loaded?

pub fn get(&self, path: &str) -> Option<Module>

Snapshot a loaded module. Returns None if not yet loaded.

pub fn begin_load(&self, path: &str) -> Result<(), ModuleError>

Begin loading path. Pushes onto the load stack and returns Err(Circular) if the path is already on the stack.

pub fn finish_load(&self, module: Module)

Finish loading path — remove from load stack, store final module bindings.

pub fn abort_load(&self, path: &str)

Abort a load (e.g., after an error during eval). Drops the path from the load stack so retries can succeed.

pub fn len(&self) -> usize

Number of fully-loaded modules. Useful for tests + tooling.

pub fn is_empty(&self) -> bool
