> Currently Rust's Value::Enum and Value::Union use i32 (i.e. signed int) for their index [fields|https://github.com/apache/avro/blob/49c6e1067c937d066503be9c7f4032fb03f67474/lang/rust/src/types.rs#L61-L74]:
> {code}
>     /// An `enum` Avro value.
>     ///
>     /// An Enum is represented by a symbol and its position in the symbols list
>     /// of its corresponding schema.
>     /// This allows schema-less encoding, as well as schema resolution while
>     /// reading values.
>     Enum(i32, String),
>     /// An `union` Avro value.
>     ///
>     /// A Union is represented by the value it holds and its position in the type list
>     /// of its corresponding schema
>     /// This allows schema-less encoding, as well as schema resolution while
>     /// reading values.
>     Union(i32, Box<Value>),

> Since they cannot be negative it would be better to change them to u32 (unsigned int).
