Description

This is a tracking issue for Duration::{ZERO, is_zero} (#![feature(duration_zero)]). Proposed in RFC 2814 which got closed just because such a small change does not require an RFC. Proposed again and implemented in #72790.

impl Duration { pub const ZERO: Duration; pub const fn is_zero(&self) -> bool; }

Steps

• Implement (core/time: Add Duration methods for zero #72790)
• FCP
• Stabilization PR (Stabilize duration_zero. #84084)

Unresolved questions:

• Also add an associated constant ZERO? yes. done
• Should the associated constant be preferred over the zero function? yes, zero() is removed.
