Here's where we are now with racket2nix:
I'm able to install but not actually build drracket and all its
dependencies. I pull down the zip files, run raco install --no-setup, and
the files are all there in their respective share/racket/pkgs, and
share/racket/links.rktd is updated. Awesome!
Get-size should work, can you provide a example that illustrates the
The only tricky bit is that the actual size of a widget is only computed
after it is shown. Here is an example:
(define toplevel (new frame% [label "hello"]
Is it possible to get the current size (width and height) of a panel% from
racket/guilty? I haven't been able to figure out a way. I set a min-width and
min-height in my panel and allow them to be stretchable. If they do stretch, I
want to be able to know their current size. Sending get-size or
You can create a thread and wait simultaneously on the place channel
value and also on some channel that the various workers use to check
in and see if a value is available. Here's a very simple instantiation
of this idea.

I understand you'd need the Custom Allocator which is

Yes, as long as you implementation covers the back-end parts of these

What about totally different approach to Rust and Racket interaction:
Racket is trying to move to Chez Scheme.
The C part of Chez Scheme is about 16k lines.
Translating (at least) some of that to Rust might be an interesing project.
