Crate pb_jelly_gen

source ·
Expand description

pb_gen generates Rust bindings for proto2 and proto3 files. It’s intended to be used with pb_rs.


Complete examples can be found in the examples crate, or the pb-test crate of the protobuf_rs workspace.

In a nutshell 🥜

You can include pb_gen in your Cargo project, by including it as a [build-dependency] in your Cargo.toml

pb-gen = "0.1"

Then from a script, use either the GenProtos builder struct, or the gen_protos convience function to specify where your protos live, and where the generated code should be put. ```no_run use pb_jelly_gen::GenProtos;

fn main() -> std::io::Result<()> { GenProtos::builder() // output path for our generated code .out_path(“./gen”) // directory where our protos live .src_path(“./protos”) // delete and recreate the out_path directory every time .cleanup_out_path(true) .gen_protos();

Ok(()) }


  • A builder struct to configure the way your protos are generated, create one with GenProtos::builder()


  • A “no frills” way to generate Rust bindings for your proto files. src_paths is a list of paths to your .proto files, or the directories that contain them. Generated code it outputted to <current crate's manifest>/gen.
