Struct InMemorySourceProvider 

pub struct InMemorySourceProvider { /* private fields */ }

An in-memory SourceProvider backed by a HashMap.

Useful for testing and environments without filesystem access. Keys are stored and looked up exactly as provided — there is no path normalization. The caller controls both the registered keys and the import paths, so they are responsible for making them match.

resolve_path joins the parent directory of from with import_path, appends .orr, and does a direct HashMap lookup on the result.
