DjW ddZddlZdejdejdedefdZded edefd Zy) uThe hot scoring kernel, shared by the pure-Python and compiled builds. This module is ordinary Python with no third-party imports: it runs as-is on PyPy and in pure-Python installs. When a compiled wheel is built, ``_kernel.pxd`` supplies C type declarations for these same functions and Cython compiles this file to native code — the ``.py`` stays the one and only implementation. Note: ``from __future__ import annotations`` is intentionally omitted to match the modules mypyc compiles, which import from here. ``dot_packed`` reads the profile's parallel ``array('i')`` buffers rather than its dense 65536-entry table. Compiled, that is the difference between a gather through a Python list and a C loop over two contiguous int32 buffers. The interpreter pays for it — ``array`` indexing boxes an int where a list returns a cached one — which is the trade this build makes deliberately.

The bound is the caller's to keep --- see :class:`~chardet.models.BigramProfile`, which documents the input limit that makes it hold. :param nonzero: Bigram indices with non-zero weight. :param freq: Dense 65536-entry weight table. :returns: An ``(idx, vals)`` tuple of ``array('i')`` buffers. r r)arrayrr )rrrr r s r pack_profiler'sc ;;sQC 3w< /D G A 1X#wqz"Q# ;;sG $d **r)__doc__rbytesintrlisttuplerrr rsR$ EKKu{{5S"+$+d+u+r
