A ProtoEnum<E> can be implicitly constructed from, and explicitly converted to an E. Values can be copied, assigned, compared for equality, and streamed.
Example
Given a proto definition enum Color { RED = 0; BLUE = 1; GREEN = 2; }:
auto e = spanner::ProtoEnum<Color>(BLUE);
assert(Color(e) == BLUE);
Constructors
