Trait snec::Entry

pub trait Entry: Sized {
    type Data;

    const NAME: &'static str;
}

Trait for type-level identifiers for config entries.

All implementors should be uninhabited types, as the creation of a type implementing Entry doesn't make sense: it's just a type-level marker identifying a configuration field. There are two ways to create such a type:

enum MyUninhabited {}
// Works only on the nightly version of the compiler as of Rust 1.46
struct MyUninhabited (!);

The first one is recommended, as it works on the stable version of the compiler. When the ! type gets stabilized, the second could be used as well, depending on your preference.

Associated Types
