Rust: error in record with resource

[omersadika]

An example for a wit file that cause the error:

package test:test

interface test-import {
  resource resource-a {
    constructor(id: u32)
  }

  record record-a {
    resource-a: resource-a,
    resources: list<resource-a>,
  }

  resource resource-b {
    make: static func(record-a: record-a)
  }
}

world test-world {
  import test-import

}

With this rust code:

wit_bindgen::generate!({
    world: "test-world",
});

I get the following error:

error[E0507]: cannot move out of `*resource_a0` which is behind a shared reference
 --> src/lib.rs:1:1
  |
1 | / wit_bindgen::generate!({
2 | |     world: "test-world",
3 | | });
  | |  ^
  | |  |
  | |__`*resource_a0` moved due to this method call
  |    move occurs because `*resource_a0` has type `ResourceA`, which does not implement the `Copy` trait
  |
note: `ResourceA::into_handle` takes ownership of the receiver `self`, which moves `*resource_a0`
 --> src/lib.rs:1:1
  |
1 | / wit_bindgen::generate!({
2 | |     world: "test-world",
3 | | });
  | |__^
  = note: this error originates in the macro `wit_bindgen::generate` (in Nightly builds, run with -Z macro-backtrace for more info)

For more information about this error, try `rustc --explain E0507`.
error: could not compile `wasm-component-test` (lib) due to previous error

The combination that cause the error is a field of a resource and a another field with a list of the same type resource. If I remove one of the field, it compiles with no error.

Thanks for the report! I think this should be fixed by #669
