Message with enum field containing keyword generates illegal code.

[peterhuene]

Repro Steps

Compile the following proto file:

syntax = "proto3";

package Example;

enum E {
  in = 0; // Uses the Rust 'in' keyword
}

message M {
  E e = 1;
}

Expected Results

The generated Rust code compiles.

Actual Results

The enum E is generated correctly:

#[derive(Clone,PartialEq,Eq,Debug,Hash)]
pub enum E {
    value_in = 0,
}

However, the following methods of M reference E::in instead of E::value_in:

• clear_e
• compute_size
• write_to_with_cached_sizes

This leads to three compilation errors: expected identifier, found keyword.

Thanks for the quick response, @stepancheg!

You are welcome! Going to backport it to stable branches now.
