It is not possible to assign a Duration to a const variable

[carllerche]

The struct fields are currently not pub making it impossible to assign Duration to a const variable.

Given that Duration is essentially timespec, it seems like it might be a good idea to make the struct fields public.

There's a legit timespec in liblibc by the way. I don't think the field sizes are compatible, though.

Can this wait for Compile Time Function Evaluation to be implemented properly? It seems like that would be the correct solution to this problem (unless having the fields public is otherwise desirable).

This is still true today.

Sample program:

use std::time::Duration;

const MINUTE: Duration = Duration::new(60, 0);

fn main() {}

This is basically always going to be true until const fn is stable, since things are now stable, so there's not much we can really do here, so I'm giving this a close.
