Support rename rule for union body members #751

@emilio What's the time table for getting something like this into a release? |

This needs a test, and I think the option naming could be more consistent? But let me know if you feel strongly, I guess just rename_fields could be seen as renaming the foo in Bar { foo: i32, bar: i32 }, even though it wouldn't.
In terms of getting it to a release, once it's merged I'm happy to publish it right away.

So this is not for Rust unions (as in union Foo {} but C/C++ unions in an enum). I think this should just be rename_fields for consistency with config.{struct,union}.rename_fields, wdyt?

Maybe rename_variant_name_field would be more explicit? I dunno.

If you can elaborate a bit on your use case it'd be great, too (maybe you can post an example of what you want to do exactly and how the renaming interferes?) |

Whenever I run 'cargo test' I get errors like " panicked at 'build should succeed: CargoExpand("expand-dep", Compile("" which seem unrelated to my changes. I looked at contributing.md and only saw something about installing cython, which I did. |

On which OS? Does running |

Thanks, that ended up being the issue! I think this should work now. Let me know if I need other tests. |

Ah, rustfmt is complaining about the trailing whitespace, but I can address manually, assuming all other tests pass. |
I am trying to use C++ macros to generate accessors for the fields in a rust enum. Since they are converted to SnakeCase by default, its impossible to write a macro that does this using only the original enum variant name.
Can we add an option to support different rename rules for the union body members as well?
