class LazyNamespaceMeta

Bases: type

Lazy namespace meta.

class LazyNamespace

Lazy namespace.

Subclasses declare dependencies (a list of import names) and optionally dependency_group (the matching pdstools[<extra>] extras group). Method calls trigger a lazy dependency check that raises MissingDependenciesException with a friendly install hint when a required package is missing.

Attribute access on missing methods (e.g. ns.some_method without calling) also triggers the dependency check, so introspection (hasattr, dir) surfaces missing-dep errors uniformly instead of returning a confusing AttributeError.

dependencies: list[str] | None

dependency_group: str | None

check_dependencies()

Check dependencies.

__getattr__(name: str)
