Tracking Issue for `duration_new_checked`

[jmillikin]

Feature gate: #![feature(duration_new_checked)]

This is a tracking issue for Duration::new_checked() and Duration::new_unchecked(), which provide panic-free constructors for core::time::Duration.

ACP: rust-lang/libs-team#117

Public API

impl core::time::Duration {
    // Returns `None` in cases where `Duration::new()` would panic
    pub const fn new_checked(secs: u64, nanos: u32) -> Option<Duration>;

    // Does not check for nanosecond overflow, enabling free conversion of known-good values.
    pub const unsafe fn new_unchecked(secs: u64, subsec_nanos: u32) -> Duration;
}
