Using rust types with flutter rust bridge

[Likho]

Hi I am new to rust and flutter. I have a function that returns the type below

type Wallet = Arc<
    Mutex<
        Box<
            dyn WalletInst<
                'static,
                DefaultLCProvider<'static, HTTPNodeClient, ExtKeychain>,
                HTTPNodeClient,
                ExtKeychain,
            >,
        >,
    >,
>;

Running flutter_rust_bridge_codegen for my fuction returns 'Failed to parse function output type Result<Wallet, Error>. How do I handle rust types in flutter_rust_bridge. Thanks

Well, Arc and Mutex and maybe dyn are not supported - you know, they cannot be serialized. What about creating custom structs and pass them around?

Smart pointers are not supported yet (they are part of #293), but if you must use them you can create a raw pointer from them and use a newtype struct to wrap it.

Thank you, I will read more on this. The documentation does not get into much detail about importing pub structs with private fields, is this supported yet?

For now all exported Rust structs must only have public members, but I'm working on something to relax this restriction.
