This page analyzes the code size impact of using components from the
``pw_bytes`` module.

Size report: using ByteBuffer vs. manual manipulation
-----------------------------------------------------
The following report compares the code size of using
:cpp:class:`pw::ByteBuffer` for constructing and parsing a simple byte sequence
versus manually performing similar operations with ``std::memcpy`` and bitwise
logic for endianness.

:cpp:class:`pw::ByteBuffer` can offer improved type safety and convenience,
potentially at a small code size cost for very simple operations, but can lead
to more maintainable and less error-prone code for complex byte manipulations.
