tilelang.cuda.intrinsics.sparse_layout
======================================

.. py:module:: tilelang.cuda.intrinsics.sparse_layout

.. autoapi-nested-parse::

   Layout metadata for 2:4 semi-structured sparsity.

   Shared contract between the example sparse compressor (``examples.gemm_sp.sparse_utils``) and the
   CUDA ``mma_sp`` code generator. Depends only on the leaf ``dtypes`` module so it
   can be pulled into the codegen import path without touching the language facade.
