Trait Max

pub trait Max {
    const MAX: Self;
}

Defines the maximum value of a type.

Required Associated Constants

const MAX: Self

The maximum value of 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.

Implementations on Foreign Types

impl Max for bool

const MAX: bool = true

The maximum value of a bool: true.

impl Max for char

const MAX: char = '\u{10ffff}'

The maximum value of a char: '\u{10ffff}'.
