Overview

ZeroBuf is a replacement for FlatBuffers, resolving the following shortcomings:

Direct get and set functionality on the defined data members
A single, in-memory buffer storing all data members, which is directly serializable
Usable, random access to the the data members
Zero copy of the data used by the (C++) implementation from and to the network

V1 Features

Storage of (u)int[8,16,32,64,128]_t, float, double single elements, fixed size arrays and dynamic arrays
Access to arrays using raw pointers, iterators, std::array and std::string/std::vector

Header in producer endianness: version (4b)
Data UUID (16b)
fixed-elem PODs: stored in-order at start of array
dynamic arrays/std::vector, std::string:
- offset (8b), size (8b) stored in place
- data at offset after all items at 4b boundary
static arrays: data in place
arrays: returned as ptr, iter, copied std::vector
getter/setter generated with hard-coded offsets
Nested classes are handled in the same way as dynamic arrays
saved in an atomic ptr for concurrent reallocs

arrays can have an optional fixed size specified as part of the type, e.g., matrix:[float:16] for a 16 value float array
