no field `st_mtimensec` on type `rustix::fs::Stat`

Hi,

This has started to happen recently,

   Compiling gix-index v0.40.0
error[E0609]: no field `st_mtimensec` on type `rustix::fs::Stat`

See for example, http://www.ki.nu/pkgsrc/reports/current/NetBSD-9.0/20250505.0626/starship-1.23.0/build.log or, http://www.ki.nu/pkgsrc/reports/current/NetBSD-9.0/20250505.0626/mise-2025.5.0/build.log

This seems to be related to #1170

But, I don't know exactly what has changed recently.

Any help would be appreciated, thank you.

I found this in the rustix::fs CHANGES file:

On NetBSD, the nanoseconds fields of [`Stat`] have been renamed, for consistency
with other platforms:

so the NetBSD special case can be removed:

Thanks! I missed the need for such a change when reviewing and merging #1949. The upgrade of rustix to 1.* came in at 68e6b2e. I've reproduced this gix-index bug on NetBSD 10.1 amd64 by installing the gitoxide crate from crates.io, as well as by running cargo build. Here's a log showing the latter. The patch in #2005 fixes the problem, allowing the build to succeed, as this other log shows.
