API Reference

This section is intentionally organized by import boundary, not by internal implementation file.

Modules

Module	What it exports
shapix	Lightweight root API: dimension symbols, structure symbols, DtypeSpec, make_array_type, make_array_like_type, check, check_context, and __version__
shapix.numpy	NumPy array aliases, Like aliases, ScalarLike aliases, Structured, ArrayLike, and make_scalar_like_type
shapix.jax	JAX array aliases, JAX Like aliases, NumPy ScalarLike re-exports, make_scalar_like_type, Tree, and Structure
shapix.torch	PyTorch array aliases, Torch Like aliases, NumPy ScalarLike re-exports, and make_scalar_like_type
shapix.cupy	CuPy array aliases, CuPy Like aliases, NumPy ScalarLike re-exports, and make_scalar_like_type
shapix.optree	Explicit Tree backend using OpTree plus Structure
shapix.claw	Thin wrapper around beartype.claw.beartype_this_package

Important boundaries

• The root shapix import is optional-dependency-safe and does not require NumPy.
• Tree is not exported from the root module. Import it from shapix.optree or shapix.jax.
• make_scalar_like_type is not exported from the root module. Import it from shapix.numpy or a backend module that re-exports it.
