Rust-protobuf generates code with several clippy warnings. These warnings are hard to fix, they bother rust-protobuf users, and they actually do need to be fixed (because I know the code is correct).

So the best way to fix the issue in rust-protobuf with clippy would be probably to tell clippy to ignore all clippy warning in some file. However as I understand there is no way to do that.

Clippy could ignore files with comments like "this file is generated" or "ignore clippy".

Note that generated code must be valid even if clippy is not used.
