seekdir() support

[nrath-js]

Is it in principle be possible to add seekdir() support, or is there something fundamental that would prevent that?

If it can't be added directly, is there any way I could implement my own seekdir() but continue to use Rustix's Dir structure, or would I have to roll my own version of opendir(), closedir() and readdir() as well?

In principle, it is probably possible. I'm not aware of anything fundamental blocking it.

If you only need Linux support, you could probably implement your own seekdir using rustix::fs::seek/lseek. If you want portable support, it would need to be added to Dir.
