This is the portion of #797 which is related to
CallbackConverter
changes.It makes use of a
run_callback
function, which takes a closure to execute. The closure must return aPyResult
.A change of this fashion was originally necessary for #797. However I think it's good independent of #797, because a lot of the code is easier to read after these changes (in my opinion). Many
match
statements have been replaced with?
as a result.I factored this out because I think #797 still might need more design before we can settle.
