third party lib, doesnt throw errors nor generate files

[abdelaziz-mahdy]

Describe the bug

i am trying to create mapping to polars, but the generate function works but doesnt create the mapping so i am confused

Steps to reproduce

Hint: A simple way to reproduce is to clone and modify the https://github.com/fzyzcjy/flutter_rust_bridge/tree/master/frb_example/dart_minimal example package according to your needs.

1. updated the frb_example/dart_minimal/flutter_rust_bridge.yaml to have rust_input: polars
2. run cd rust && cargo add polars && cd ..
3. run flutter_rust_bridge_codegen generate

Hi! Thanks for opening your first issue here! :smile:

[fzyzcjy]

Hi, could you please provide a minimal reproducible sample?

Btw, polars may be too complex to be auto scanned by the experimental "scan whole third party package" feature.

And you may be interested in: https://github.com/Desdaemon/polars_dart

[abdelaziz-mahdy]

this is an example repo, https://github.com/abdelaziz-mahdy/polars_dart

i would love to have the auto scan working in general since that will make migration rust crates binding so much easier and that will improve the dart platform in general, so i am interested to make it work

I think so, that would be quite convenient. And, even if it cannot handle 100% cases, let it handle a large portion of trivial things would also be beneficial.

Looked at the logs. Seems

[2024-09-19T23:27:04.134Z DEBUG /Users/AbdelazizMahdy/.cargo/registry/src/index.crates.io-6f17d22bba15001f/flutter_rust_bridge_codegen-2.4.0/src/library/codegen/parser/hir/tree/transformer/pub_use_transformer.rs:155] transform_module_by_pub_use_single skip `PubUseInfo { namespace: Namespace { joined_path: "polars_core::export" }, name_filter: None }` since cannot find mod

i.e. the polars package is almost empty and only exports polars_core. On the other hand, frb currently has not implemented such complex cross-multiple-third-party-crate-import things.

Oh okay, guess I will wait for it to get fixed when you have time to do so,

Or create my own API around it

Thank you for the awesome package and looking forward to scanning to be improved

[fzyzcjy]

You are welcome! I guess this may be a bit nontrivial so cannot estimate the time to implement it.
