This module provides helper classes and functions for working with Python's type system, including workarounds for type checker limitations and utilities for runtime type inspection. ) dataclass)AnyGenericcastget_args get_origin) TypeAliasTypeTypeVarTT)infer_variancec@seZdZdZdS)TypeExpressionaaA workaround for type checker limitations when using complex type expressions. This class serves as a wrapper for types that cannot normally be used in positions requiring `type[T]`, such as `Any`, `Union[...]`, or `Literal[...]`. It provides a way to pass these complex type expressions to functions expecting concrete types. Example: Instead of `output_type=Union[str, int]` (which may cause type errors), use `output_type=TypeExpression[Union[str, int]]`. Note: This is a workaround for the lack of TypeForm in the Python type system.

This class represents a value that is definitely present, as opposed to None. It's part of the Maybe pattern, similar to Option/Maybe in functional programming, allowing distinction between "no value" (None) and "value is None" (Some(None)). valueN)r rrrr __annotations__rrrrr9s rMaybeN callable_cCst|dt|S)zExtract a human-readable name from a callable object.
