Error with rust-nightly: type annotations needed for `Box<_>` about time

[dessalines]

For me it was as simple as running cargo update. Make sure you open issues if there's a crate you're using that hasn't updated.

Nevermind, I see that this has been fixed, deps just need to be updated.

@dessalines, I am running into this issue at present with both nightly and 1.78 docker images. How did you address it?

Edit: even thought time is only a recursive dependency, adding it to my Cargo.toml fixed this issue.

time = "0.3.36"

If I understand it correctly, the code used to compile but doesn't with newer versions of the compiler? How is this not an issue in rustc? Something changed that broke backwards compatibility and that should not happen, right?

I haven't looked into this at all, but my understanding from discussions elsewhere is that this was fixed by #671. time was caught in a crater run when a new trait implementation was added to the standard library. While it is a breaking change, it is considered acceptable breakage because the alternative is never adding any trait implementations or methods.

[iitalics]

would it be possible to backport a fix for this?

[jhpratt]

@iitalics That's impossible.
