Hello!

Not sure if this is the right place to send the patch, but here it is.

I reported the bug earlier and expected to see it go live on debbugs, but apparently the process is not (that) automatic.

I subscribed for the devel list, but, if you have any comments on this patch, please drop me an email as well.

Cheers!
Yordan Miladinov

Subject: [PATCH] Fix apostrophe handling in rust-ts-mode

* lisp/progmodes/rust-ts-mode.el (rust-ts-mode--syntax-table)
  Update the syntax table to treat the apostrophe character as
  defining a string, similar to c-ts-mode.  This fix addresses issues
  with functions that rely on scan-lists.
