Weaken requirements to a number of enum variants #15

Closed blackbeam closed 5 years ago

Hi.

This PR is a straightforward fix for the issue where the following snippet of code won't compile with error: cannot be implemented for enums with less than two variants:

#[derive(Read, Write)]
enum Stream {
    Some(SomeStream),
    #[cfg(features = "other")]
    Other(OtherStream),
}
