Sorry late to the party. Here is my start at porting polars to R. [https://github.com/sorhawell/minipolars/blob/main/test/example_minipolars.md](https://github.com/sorhawell/minipolars/blob/main/test/example_minipolars.md) Are anyone still active on this endevour? I would very much like to collarborate. @[lmeninato](https://github.com/lmeninato)...

I would guess it is because it would be the wrong concept to use. Generic functions concept should be resolved at compile time. If somehow exporting a generic function family...

I suggest this fix #151

I might have another quickfix I was concidering to try out. If given that no two exported structs can have the same name, then the R side class name without...

Maybe it will always be a very deep rabbit hole to produce an Robj-tag, that can proove the ExternalPointer is pointing to the exact correct struct. Likely the tag should...

currently I use the Rpackage xptr to extract the pointer as a string (due to no u64 type) and then [this generic](https://github.com/sorhawell/minipolars/blob/7bb361aa5a94a8aa9284ab0d6e444e199db84553/src/rust/src/utils/wrappers.rs#L40) to reinterpret which works good enough for me...

Likely 'close, but no cigar'. It seems I get the original error. Maybe an intended edit is missing in the new function check_external_ptr_type() `Err( ExpectedExternalPtrType( ExternalPtr.set_class(["MyStruct"], "helloextendr::MyStruct", ), )` [I...

I did not manage to make my previously failing cargo tests work. Not sure why, perpaps my cargo tests have a slightly different env or r_engine() is different or I'm...

Oh I forgot. There is comment somewhere about it in the test. I built the package manually to perform the cargo test wit r_engine() a week ago. But I have...

cargo tests were alright, just needed to build package fully and not use rextendr::document(). @Ilia-Kosenkov > If you can think of another test case worth adding to the repo, let...
