Trait SerialPrimitive 

pub trait SerialPrimitive: Copy + Ord {
    const HALF: Self;

    // Required methods
    fn wrapping_add(self, rhs: Self) -> Self;
    fn wrapping_sub(self, rhs: Self) -> Self;
}

An unsigned integer type that can serve as the underlying storage for a serial number.

Already implemented for u8/u16/u32/u64/u128/usize; usually no manual implementation is needed.

Required Associated Constants

const HALF: Self

The “half cycle” size of the wraparound space, i.e. 2^(BITS-1).

Per RFC 1982 the largest valid addend is HALF - 1; HALF itself already lies in the “undefined” region. It is also the dividing point that distinguishes the “front half / back half” of a cycle during comparison.

Required Methods

fn wrapping_add(self, rhs: Self) -> Self

Wraparound addition.

fn wrapping_sub(self, rhs: Self) -> Self

Wraparound subtraction.

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
