Description

built from master:

>~/src/flatbuffers/grpc/samples/greeter$ ../../../build/flatc --grpc --rust greeter.fbs
../../../build/flatc: warning: GRPC interface generator not implemented for Rust

I know Rust support is new so I wasn't expecting this right away but it would be cool. I use grpc-rs so I was looking for support for that crate but others use grpc-rust.

Research direction
This tracking issue requests adding Rust gRPC code generation to the flatc compiler. The user mentions grpc rs and grpc rust as potential target crates. To implement, one should study the existing C++ gRPC generation in the FlatBuffers codebase (e.g., in src/idl gen grpc.cpp) and adapt it for Rust. The issue has been open since 2018 with no PRs, indicating a significant effort but no current progress.
