In-place memory manager, mmap (was: Fastest way to store ints and floats on disk)

Hi, I've got an "in-place" memory manager that uses a disk-backed memory- mapped buffer. Among its possibilities are: storing variable-length strings and structures for persistence and interprocess communication with mmap. It allocates segments of a generic buffer by length and returns an offset

Struct class random access

struct.Struct lets you encode Python objects into structured memory. It accepts a format string, and optionally a buffer and offset to/from which to read/write the structure. What do you think of random access for the results? (unproduced) >>> packer= struct.Struct( 'IIIf255p' ) >>> packer.pack_i
