* fix(build): Prevent duplicated client/server generated code The tonic-build process collects up RPC services as they are provided by prost, before writing them out as part of the finalization step for a given protocol buffer package. In the case of imported protocol buffer packages, there may be RPC services included by import in addition to those in the top-level package. Therefore it is necessary to make sure each set of client/server services gathered by tonic-build is cleared after the finalization process for a given protocol buffer package, otherwise they will be incorrectly aggregated as the generation process proceeds through the subsequent packages. * Test case for duplicated client/server generated code A simple test case that will fail to build without a fix to prevent RPC services being duplicated into inappropriate modules (that related to particular protocol buffer packages). * Additional test case for included_service Introduces an additional case that captures making sure services defined before including a package with additional services doesn't incidentially clear such precursor services from the including package. * Fix unnecessary newline to keep `cargo fmt` happy
tonic-build
Compiles proto files via prost and generates service stubs and proto definitiones for use with tonic.
Features
- rustfmt: This feature enables the use of rustfmt to format the output code this makes the code readable and the error messages nice. This requires that rustfmt is installed. This is enabled by default.
