Trait StatType

pub trait StatType<T> {
    type Bound: StatBound<T>;

    const STAT: Stat;
}

StatType define the bound of a given statistic. (e.g. Max is an upper bound), this is used to extract the bound from a Precision value, (e.g. p::bound<Max>()).

Required Associated Constants

const STAT: Stat

Required Associated Types

type Bound: StatBound<T>

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.
