Tracking issue for duration_float

[newpavlov]

Rust PRs: #52813, #59102

This feature adds the following float related methods to Duration:

• as_secs_f64(&self) -> f64
• as_secs_f32(&self) -> f32
• from_secs_f64(secs: f64) -> Duration
• from_secs_f32(secs: f32) -> Duration
• mul_f64(self, rhs: f64) -> Duration
• mul_f32(self, rhs: f32) -> Duration
• div_f64(self, rhs: f64) -> Duration
• div_f32(self, rhs: f64) -> Duration

div_duration methods are tracked in #63139.

What needs to happen before this can be stabilized?

f64 vs f32

The only sane options are "have versions for both", or "f64 because it's more general and people can always downcast." You can't fit a billion nanoseconds into the 24 bit significand of a f32.

Also, yes, what needs to happen for this to stabilize?

I guess we probably should rename methods to as_f64_secs, from_f64_secs and div_duration_f64, so we will have an option to add analogous f32 methods.

What can I do to help?

I guess we probably should rename methods to as_f64_secs, from_f64_secs and div_duration_f64, so we will have an option to add analogous f32 methods.

as_secs_f64 and from_secs_f64 would be more consistent.
