py: Start implementing "struct" module. Only calcsize() and unpack() functions provided so far, for little-endian byte order. Format strings don't support repition spec (like "2b3i"). Unfortunately, dealing with all the various binary type sizes and alignments will lead to quite a bloated "binary" helper functions - if optimizing for speed. Need to think if using dynamic parametrized algos makes more sense. 2014-04-10 03:45:38 +03:00			`import struct`

modstruct: Refactor to support both LE and BE packed structs. 2014-04-10 22:19:32 +03:00			`print(struct.calcsize(">bI"))`

modstruct: Basic implementation of native struct alignment and types. 2014-04-11 03:47:21 +03:00
