macro_registry

macro_registry is shared infrastructure for proc-macro crates that need:

• call-site source/module-path resolution,
• file-level AST analysis cached per source file, and
• lightweight static registries keyed by module path.

It is used by statum-macros to resolve #[state] and #[machine] declarations from macro call sites without duplicating registry/cache logic.

Modules

• callsite: wrappers around module_path_extractor for source info and module path lookup.
• analysis: memoized syn::File analysis for enums/structs in a source file.
• registry: generic registry traits and loading helpers.

Example

use macro_registry::callsite::{current_module_path, current_source_info};

let module_path = current_module_path();
let source = current_source_info();
println!("module={module_path} source={source:?}");
