CFB Encoding

CFB (Canonical FlatBuffers) is a restricted variant of FlatBuffers for producing unequivocal transfer syntax.

Usage

Install the code geneartor as commane line utility:

pip install -U cfbc

First generate bfbs file from fbs:

flatc -b --schema example.fbs

Then generate rust files from bfbs:

cfbc example.bfbs

Use Verifier with flatbuffers rust

• Add the generated <name>_generated_verifier.rs to the project in the same directory with the file <name>_generated.rs generated by flatc -r.
• Add crate flatbuffers-verifier as a dependency in Cargo.toml.
• Use the same version of flatbuffers as in flatbuffers-verifier.

flatbuffers-verifier = { git = "https://github.com/nervosnetwork/cfb" }
flatbuffers = { git = "https://github.com/google/flatbuffers", rev = "4f10da8d99c1a7bc8c9c7d06d2092a689f171d29" }

The crate flatbuffers-verifier defines a function get_root, which is intended to replace the function with the same name in flatbuffers. This function will verify the buffer, and returns a Result to indicate whether the buffer is valid.
