Update PyO3

[mgorny]

Update PyO3 using cargo update.

This is the minimal change needed to address #261.

[mgorny]

Sorry, no clue how to deal with these issues.

[mgorny]

Hmm, I suppose this means that PyO3 doesn't support 2.5 year old Rust anymore.

[samuelcolvin]

Ye, we restrict the version to (I think) 1.76 in pydantic and no one has complained.

[samuelcolvin]

@davidhewitt would know more.

We should set the min version in cargo to whatever PyO3 supports.

[davidhewitt]

It's possible but you'll have to downgrade packages like once_cell to versions still compatible with 1.56

The next PyO3 release will support a minimum of 1.63

[mgorny]

Ok, so apparently cargo update (at least in 1.56.0) doesn't support selecting newest correct versions automatically, so I've instead limited the change to updating PyO3 itself.

I ran into the same issue, created a fork with dependabot enabled and it created over 15 Pull Requests. All of them are failing during ci / lint and ci / check.

One of the big ones is setup-python action, the one used in this repo is way beyond deprecated:

• Bump actions/setup-python from 1 to 5

@mgorny Can you also apply the changes from this PR: https://github.com/gaby/watchfiles/pull/9/files#diff-b803fcb7f17ed9235f1e5cb1fcd2f5d3b2838429d4368ae4c57ce4436577f03fR65

[samuelcolvin]

thanks so much, I'll make more changes in later PRs.

[mgorny]

Thanks!
