Trait Width 

pub trait Width: Ord + Clone {
    type Output: Unsigned + Integer + Clone;

    // Required methods
    fn min_value() -> Self;
    fn max_value() -> Self;
    fn width(lower: &Self, upper: &Self) -> Self::Output;
}

Limits of a bound for which the distance between min_value() and max_value() can be represented in the type Output.

Required Associated Types

type Output: Unsigned + Integer + Clone

Required Methods

fn min_value() -> Self

Smallest value representable by the range.

fn max_value() -> Self

Largest value representable by the range.

fn width(lower: &Self, upper: &Self) -> Self::Output

The result might be infinite depending on the underlying type, for example floating types.

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.
