Tracking Issue for `saturating_int_assign_impl`

[kellerkindt]

Feature gate: #![feature(saturating_int_assign_impl)]

This is a tracking issue for adding basic integer operations to the Saturating Wrapping type:

let mut value = Saturating(2u8);
value += 3u8;
value -= 1u8;
value *= 2u8;
value /= 2u8;
value %= 2u8;
value ^= 255u8;
value |= 123u8;
value &= 2u8;

As well as

See #93208 (comment). No longer within the scope of this feature:

let mut value = Saturating(2u8);
let _: Saturating<u8> = value + 3u8;
let _: Saturating<u8> = value - 1u8;
let _: Saturating<u8> = value * 2u8;
let _: Saturating<u8> = value / 2u8;
let _: Saturating<u8> = value % 2u8;
let _: Saturating<u8> = value ^ 255u8;
let _: Saturating<u8> = value | 123u8;
let _: Saturating<u8> = value & 2u8;

Steps / History

• Implement basic Saturating type Tracking Issue for Saturating type #87920
• Proposal for this implementation: Tracking issue for core::ops::*<T> on Saturating<T> / Wrapping<T> type #91586

Unresolved Questions

• Is this reasonable?

An implementation for the Wrapping type is planned as follow up.
