Function enum_block 

fn enum_block(
    member: &Member,
    mixin: Option<&str>,
    members: &[(String, String)],
) -> String

Renders one enum.Enum subclass and its members.

The members carry their values, because for a str enum the value is the API — atune.TrialState.COMPLETE == "complete" is the property the class exists for, and a stub that wrote COMPLETE: str would hide it.
