refact(async-vfs): move to tokio

[attila-lin]

as async-std has been discontinued. move to tokio

hi @Fredrik-Reinholdsen sorry for the ping!

I'm trying to move your async-vfs to tokio, but the ci failed. But I tried in windows. Do you have some idea?

Hi there, thanks for the PR.

Just a quick heads up: I have to admit I don't feel confident enough in my expertise with async rust in general and tokio in particular to adequately review and support a tokio variant. I may even have to sunset the current async-std variant.

It might be worth looking into forking this project into a separate tokio-vfs crate.

Quick note on the CI failing: It looks like the lock file has a different version, cf. https://github.com/manuel-woelker/rust-vfs/actions/runs/14877441640/job/41777455425?pr=74
The CI pipeline uses a rather ancient cargo version, while you probably have a newer one installed.

Things to try:

1. Try updating the action versions in the github workflow here: https://github.com/manuel-woelker/rust-vfs/blob/master/.github/workflows/compile.yml
2. The other option might be to try to generate a "legacy" lockfile using an older cargo version.

Hi Manuel,
I understand, and it is your project. You do what you think is right!
Would be happy create and maintain a fork in that case since I use this for work.
Happy to help out if it remains part of this repo too of course.

Agree that the lockfile is wrong.
I could have a go at fixing the issue this weekend

@attila-lin The reason has to do with the checked out lockfile. Lockfile version 4 was stabilized in Rust 1.78, and the minimum required Rust version is 1.63 which is significantly older. You could try just manually changing the version in the lockfile to 3 instead of 4 and see if that works, because they should be backwards compatible.

The other option would be to increase the, but that I do not think is a great idea because it would be a significant jump, and it should be possible without this.

I got it. Let me try.
