"""
Mixed-module definition for the struct module.
Note that there is also a pure Python implementation in pypy/lib/struct.py;
the present mixed-module version of struct takes precedence if it is enabled.

class Module(MixedModule):
"""\
Functions to convert between Python values and C structs.
Python strings are used to hold the data representing the C struct
and also as format strings to describe the layout of data in the C struct.
The optional first format char indicates byte order, size and alignment:
@: native order, size & alignment (default)
=: native order, std. size & alignment
<: little-endian, std. size & alignment
>: big-endian, std. size & alignment
!: same as >
The remaining chars indicate types of args and must match exactly;
these can be preceded by a decimal repeat count:
x: pad byte (no data);
c:char;
b:signed byte;
B:unsigned byte;
h:short;
H:unsigned short;
i:int;
I:unsigned int;
l:long;
L:unsigned long;
q:long long;
Q:unsigned long long
f:float;
d:double.
Special cases (preceding decimal count indicates length):
s:string (array of char); p: pascal string (with count byte).
Special case (only available in native format):
P:an integer type that is wide enough to hold a pointer.
Whitespace between formats is ignored.
The variable struct.error is an exception raised on errors."""
