   :name: pw_hdlc

``pw_hdlc`` currently optimizes for robustness and flexibility instead of
binary size or performance.

The ``HDLC encode and decode`` size report shows the cost of everything needed
to use ``pw_hdlc``, including the dependencies on common modules like CRC32
from :ref:`module-pw_checksum` and variable-length integer handling from
:ref:`module-pw_varint`.

The ``HDLC encode and decode, ignoring CRC and varint`` size report shows the
cost of ``pw_hdlc`` if your application is already linking CRC32 and
variable-length integer handling. ``pw_varint`` is commonly used since it's
necessary for protocol buffer handling, so it's often already present.

.. TODO: b/388905812 - Re-enable the size report.
