Where does protobuf-codegen output my files?

[njerschow]

Hi, I'm looking to generate rust from several (>20) proto files. However I cannot figure out where they are getting generated. Please advise

Here is my build.rs:

fn main() {

    protobuf_codegen::Codegen::new()
        // Use `protoc` parser, optional.
        .protoc()
        // Use `protoc-bin-vendored` bundled protoc command, optional.
        // .protoc_path(&protobuf_gen::protobuf_gen_rust::protoc_bin_path().unwrap())
        // All inputs and imports from the inputs must reside in `includes` directories.
        .includes(&["protos"])
        // Inputs must reside in some of include paths.
        .input("protos/osmosis/gamm/v1beta1/tx.proto")
        .input("protos/osmosis/gamm/v1beta1/query.proto")
        // ... several other inputs removed
        // Specify output directory relative to Cargo output directory.
        .cargo_out_dir("outdir")
        .run_from_script();
}

All of the protos are in the protos directory, and cargo build runs without failing.

Thanks

where they are getting generated

Somewhere in target.

Can be used something like this:

include!(concat!(env!("OUT_DIR"), "/outdir/mod.rs"));

hmm, I'm still having trouble. here is my updated code

fn main() {

    protobuf_codegen::Codegen::new()
        // Use `protoc` parser, optional.
        .protoc()
        // Use `protoc-bin-vendored` bundled protoc command, optional.
        // .protoc_path(&protobuf_gen::protobuf_gen_rust::protoc_bin_path().unwrap())
        // All inputs and imports from the inputs must reside in `includes` directories.
        .includes(&["protos"])
        // Inputs must reside in some of include paths.
        .input("protos/osmosis/gamm/v1beta1/tx.proto")
        .input("protos/osmosis/gamm/v1beta1/query.proto")
        // Specify output directory relative to Cargo output directory.
        .cargo_out_dir("./target")
        .run_from_script();
}

Trust me I've searched my directory up and down, haven't found the generated files. I've changed the cargo_out_dir to a bunch of different names, sometimes the command fails if I use nested directories. Any troubleshooting advice would be greatly appreciated.

I was facing the same problem...

. cargo_out_dir("src") will create a random folder under `./target/release/build/proto-xxxx/out/src/mod.rs

instead use .out_dir("src") it will generate files under ./src/mod.rs
