Trait Num 

pub trait Num:
    'static
    + Eq
    + Copy
    + Clone
    + Debug
    + Hash
    + Bounded
    + Ord {
    type Range: Iterator<Item = Self>;

    // Required methods
    fn range(a: usize, b: usize) -> Self::Range;
    fn to_usize(self) -> usize;
    fn from_usize(v: usize) -> Self;
    fn is_valid(v: usize) -> bool;
}

Required Associated Types

type Range: Iterator<Item = Self>

Required Methods

fn range(a: usize, b: usize) -> Self::Range

fn to_usize(self) -> usize

fn from_usize(v: usize) -> Self

fn is_valid(v: usize) -> bool

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.
