pub trait PartialEnum: PartialOrd + MaybeBounded {
    // Required methods
    fn pred(&self) -> Option<Self>;
    fn succ(&self) -> Option<Self>;
}

Type for which instances can be partially enumerated.

Required Methods

fn pred(&self) -> Option<Self>

fn succ(&self) -> Option<Self>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
