- :mod:`ustruct` -- pack and unpack primitive data types
- ======================================================
- .. module:: ustruct
- :synopsis: pack and unpack primitive data types
- |see_cpython_module| :mod:`python:struct`.
- Supported size/byte order prefixes: ``@``, ``<``, ``>``, ``!``.
- Supported format codes: ``b``, ``B``, ``h``, ``H``, ``i``, ``I``, ``l``,
- ``L``, ``q``, ``Q``, ``s``, ``P``, ``f``, ``d`` (the latter 2 depending
- on the floating-point support).
- Functions
- ---------
- .. function:: calcsize(fmt)
- Return the number of bytes needed to store the given *fmt*.
- .. function:: pack(fmt, v1, v2, ...)
- Pack the values *v1*, *v2*, ... according to the format string *fmt*.
- The return value is a bytes object encoding the values.
- .. function:: pack_into(fmt, buffer, offset, v1, v2, ...)
- Pack the values *v1*, *v2*, ... according to the format string *fmt*
- into a *buffer* starting at *offset*. *offset* may be negative to count
- from the end of *buffer*.
- .. function:: unpack(fmt, data)
- Unpack from the *data* according to the format string *fmt*.
- The return value is a tuple of the unpacked values.
- .. function:: unpack_from(fmt, data, offset=0)
- Unpack from the *data* starting at *offset* according to the format string
- *fmt*. *offset* may be negative to count from the end of *buffer*. The return
- value is a tuple of the unpacked values.
