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.
flatc
)Use cmake
to create the build files for your platform and then perform the compliation (Linux example).
cmake -G "Unix Makefiles"
make -j
2. Define your flatbuffer schema (.fbs
)
3. Generate code for your language(s)
flatc
compiler to take your schema and generate language-specific code:./flatc --cpp --rust monster.fbs
Which generates monster_generated.h
and monster_generated.rs
files.
4. Serialize data
Use the generated code, as well as the FlatBufferBuilder
to construct your serialized buffer. (C++
example)
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
Rust
example reading the data written by C++

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