Required Associated Constants§

const MIN: Self

Same as the builtin MIN associated constant, except that this is NEG_INFINITY for floats instead of the minimum finite value.

const MAX: Self

Same as the builtin MAX associated constant, except that this is INFINITY for floats instead of the maximum finite value.

Required Associated Types§

type Underlying: Number

type ByteArray: Array<Item = u8>

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.
