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.
Build the compiler for flatbuffers (
cmake to create the build files for your platform and then perform the compliation (Linux example).
cmake -G "Unix Makefiles" make -j
Define your flatbuffer schema (
Generate code for your language(s)
flatc compiler to take your schema and generate language-specific code:
./flatc --cpp --rust monster.fbs
Use the generated code, as well as the
FlatBufferBuilder to construct your serialized buffer. (
Use your serialized buffer however you want. Send it to someone, save it for later, etc...
Read the data
Use the generated accessors to read the data from the serialized buffer.
It doesn't need to be the same language/schema version, FlatBuffers ensures the data is readable across languages and schema versions. See the
Rust example reading the data written by

FlatBuffers does not follow traditional SemVer versioning (see rationale) but rather uses a format of the date of the release.
