FlatBuffers is a cross platform serialization library architected for maximum memory efficiency. It allows you to directly access serialized data without parsing/unpacking it first, while still having great forwards/backwards compatibility.
cmake to create the build files for your platform and then perform the compliation (Linux example).
cmake -G "Unix Makefiles"
2. Define your flatbuffer schema (
3. Generate code for your language(s)
flatc compiler to take your schema and generate language-specific code:
./flatc --cpp --rust monster.fbs
4. Serialize data
Use the generated code, as well as the
FlatBufferBuilder to construct your serialized buffer. (
5. Transmit/store/save Buffer
Use your serialized buffer however you want. Send it to someone, save it for later, etc...
6. Read the data
