Enable Rust tag group names
Remove stray whitespace change
Rust trait definition syntax was wrong in the comment
Fix the comment for in rust.c parseStructOrEnum
Rename the 'tag_type' tag group name to be 'Typedefs / Enums' for Rust
Rust: No need to copy the name of the trait when parsing it
Rust: No need to copy the name of the module when parsing it
Rust: No need to copy the name of the struct/enum when parsing it
Rust: If we find a malformed field, do not give up on parsing the entire struct/enum but skip to the next field candidate
Rust: Ensure K_NONE is never actually ends up in the tag (this was impossible before, but now it's enforced)
Rust: Remove stray space
