Missing dependencies from ebranch

There's a lot of missing dependencies for this, we'll start working on it

First list of missing dependencies (all rust things):

Error:
 Problem 1: nothing provides requested (crate(chic/default) >= 1.2.2 with crate(chic/default) < 2.0.0~)
 Problem 2: nothing provides requested (crate(itertools/default) >= 0.11.0 with crate(itertools/default) < 0.12.0~)
 Problem 3: nothing provides requested (crate(peg/default) >= 0.8.1 with crate(peg/default) < 0.9.0~)
 Problem 4: nothing provides requested (crate(pyo3/default) >= 0.20.0 with crate(pyo3/default) < 0.21.0~)
 Problem 5: nothing provides requested (crate(pyo3/extension-module) >= 0.20.0 with crate(pyo3/extension-module) < 0.21.0~)

It seems some of these packages do exists (for example itertools), but in different versions. Does it mean with rust we need to build the same packages, but with multiple versions in parallel ?

The need for rust-itertools0.11 (https://bugzilla.redhat.com/show_bug.cgi?id=2332630) can be avoided if this pull request is merged: https://src.fedoraproject.org/rpms/python-libcst/pull-request/6 (or if the libcst source are upgraded to the latest upstream version 1.5.1).

I have updated the above pull request to also upgrade pyo3 to version 0.22. If I locally build all the rust-peg packages and this patched python-libcst, I can successfully boostrap everything on EPEL 10:

[root@03df2990fcb9 python-libcst]# mock --root centos-stream+epel-10-x86_64 --chain ../rust-peg-runtime/rust-peg-runtime-0.8.3-2.el10_0.src.rpm ../rust-peg-macros/rust-peg-macros-0.8.4-1.el10_0.src.rpm ../rust-peg/rust-peg-0.8.4-1.el10_0.src.rpm ../python-libcst/python-libcst-1.4.0-3.el10_0.src.rpm

With the latest upgrade to version 1.6.0, it now builds fine on EPEL 10 when using the rawhide branch content. See this scratch build: https://koji.fedoraproject.org/koji/taskinfo?taskID=128917853

Ping.

I can help building this on EPEL if needed (fas id: romaingeissler1a)

This bug appears to have been reported against 'rawhide' during the Fedora Linux 42 development cycle.
Changing version to 42.

Will you be able to branch and build python-libcst in epel10?
I would be happy to be a co-maintainer if you do not wish
to build it on epel10 (FAS: romaingeissler1a).

If you provide a PR that looks sensible to make this build, I'm happy to add you as a comaintainer
