Translate third-party packages

[kodjodevf]

I noticed that it exists recently but could you help me on how to use it, I am aware of having read the documentation concerning it and also the example but I am encountering some problems and also it is still unclear for especially me since I am a beginner in RUST. for the example I plan to use the crate
IS it possible to use it ?

Thank you for the hard work

Hi, you are welcome! I briefly checked that API (https://docs.rs/dom_query/latest/dom_query/struct.Document.html), and looks like it uses a lot of lifetime and borrows, which flutter_rust_bridge does not support yet (because there may be some weird semantics when using mutably borrowed type) but may support later.

However, may I firstly know your use case? As a very simple example, suppose your use case is to simply

let a = document.select("a:nth-child(3)");
let text: &str = &a.text();

Then it is totally OK to have a function like:

fn select_text(query: &str) -> String {
  document.select(query).text()
}

On the other hand, if your scenario is very complex, then I will need to know a bit and then think about what to do to handle it.

EDIT: The demo that I work with is in https://github.com/fzyzcjy/flutter_rust_bridge/tree/master/frb_example/integrate_third_party, which auto handles https://crates.io/crates/web-audio-api (a Rust api that mimics Web Audio standard but can work on native platforms).

Btw, I am going to implement reference types (borrowed types) probably in the next batch.

For that specific question, by reading the error message, maybe try Mutex<Selection> and whether it works.

But I guess that one may not work, since you are exposing a Selection to global variable and that lifetime may be a bit too long. (I do hope to see I am wrong!)

Yes that also didn't work

I really can't wait to test it and thank you once again for your hard work.

You are welcome!
