Pbjsonrpc-build
Automatically generate jsonrpsee Trait for auto-generated prost types.
Usage
[dependencies]
pbjson = "0.3"
pbjson-types = "0.3"
prost = "0.10"
prost-types = "0.10"
[build-dependencies]
pbjson-build = "0.3"
pbjsonrpc-build = "0"
prost-build = "0.10"
Next create a build.rs
containing the following
let root = PathBuf::from(env!("CARGO_MANIFEST_DIR")).join("protos");
let proto_files = vec![root.join("myproto.proto")];
// Tell cargo to recompile if any of these proto files are changed
for proto_file in &proto_files {
println!("cargo:rerun-if-changed={}", proto_file.display());
}
let descriptor_path = PathBuf::from(env::var("OUT_DIR").unwrap())
.join("proto_descriptor.bin");
prost_build::Config::new()
// Save descriptors to file
.file_descriptor_set_path(&descriptor_path)
// Override prost-types with pbjson-types
.compile_well_known_types()
.extern_path(".google.protobuf", "::pbjson_types")
// Generate prost structs
.compile_protos(&proto_files, &[root])?;
let descriptor_set = std::fs::read(descriptor_path)?;
pbjson_build::Builder::new()
.register_descriptors(&descriptor_set)?
.build(&[".mypackage"])?;
pbjsonrpc_build::Builder::new()
.register_descriptors(&descriptor_set)?
.build(&[".mypackage"])?;
Finally within lib.rs
/// Generated by [`prost-build`]
include!(concat!(env!("OUT_DIR"), "/mypackage.rs"));
/// Generated by [`pbjson-build`]
include!(concat!(env!("OUT_DIR"), "/mypackage.serde.rs"));
/// Generated by [`pbjsonrpc-build`]
include!(concat!(env!("OUT_DIR"), "/mypackage.jsonrpc.rs"));
