Do we support this syntax for code generation `Lazy<Arc<RwLock<Option<T>>>>` ?

[thaodt]

Is your feature request related to a problem? Please describe. I'm not sure if it related to this #775 In api.rs, I declare a static var like below:

pub static GLOB_DATA: Lazy<Arc<RwLock<Option<MyDataWrapper>>>> =
    Lazy::new(|| Arc::new(RwLock::new(None)));

and the struct:

pub struct MyDataWrapper {}
impl MyDataWrapper {
// ....
}

Because I got the following messages:

[2022-11-09T08:56:02Z WARN  cbindgen::bindgen::parser] Skip native::GLOB_DATA - (not `no_mangle`).
[2022-11-09T08:56:02Z INFO  cbindgen::bindgen::parser] Take native::MyDataWrapper - opaque (Struct is not marked #[repr(C)] or #[repr(transparent)].).

Describe the solution you'd like If this is relating to the issue I linked above, when I can use this feature?

Describe alternatives you've considered Otherwise is there any alternative solutions to work around it?

p/s: I'm checking examples here, but I'm confused which one served for which purposes and also the example link here is not found now, please point me out the update link if possible. I just want to check more types that this code generator can generate.

Thank you.

GLOB_DATA itself is ok

what error do you have indeed? "skip" is not an error

Hmmm, lemme check again. Because I didn't see any updates in bridge_generated.rs after running build runner for generation. Therefore I thought the message about opaque type for my struct MyDataWrapper is a problem also

[fzyzcjy]

please provide full output log. maybe somewhere else is wrong

[thaodt]

@fzyzcjy Okay, I found the problem. Im not sure why flutter_rust_bridge_codegen --version still kept the old one (1.30.0) even though in Cargo.toml I put the version 1.49.1. After updating, I got this error:

[2022-11-09T12:23:44Z DEBUG lib_flutter_rust_bridge_codegen::parser] parse_function function name: Ident(get_latest_block_hash__static_method__MyDataWrapper)

note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace
error: Recipe `gen` failed on line 16 with exit code 101

And actually Sha256Hash is [u8; 32]. Could you please advise me on this ?

[fzyzcjy]

could you please provide full information? maybe open a new issue

@fzyzcjy also, please provide me the update link for this one? I want to check more types that this code generator can generate.

Sure this is full log:

e.g. what is Sha256Hash etc please see issue template -> https://github.com/fzyzcjy/flutter_rust_bridge/issues/new?assignees=&labels=bug&template=bug_report.yaml&title=%5BBug%5D+

actually I mentioned Sha256Hash type here, but its okay. Lemme close this issue and open new bug issue.

[fzyzcjy]

and actually Sha256Hash is [u8; 32].

Indeed this is insufficient. need to at least know: where is it defined? is it pub? etc
