the trait bound XXX: RefFromWasmAbi is not satisfied

[ahaoboy]

Describe the Bug

error[E0277]: the trait bound `TestEnum: RefFromWasmAbi` is not satisfied
  --> src\lib.rs:29:1
   |
29 | #[wasm_bindgen]
   | ^^^^^^^^^^^^^^^ the trait `RefFromWasmAbi` is not implemented for `TestEnum`

Steps to Reproduce

#[wasm_bindgen]
pub enum TestEnum {
    A,
    B,
}
#[wasm_bindgen]
impl TestEnum {
    pub fn log1(self) {
        println!("log1")
    }

    pub fn log2(&self) {
      println!("log2")
  }
}

Expected Behavior

Both log1 and log2 work correctly

Actual Behavior

Since log2 uses &self, it cannot be exported to wasm

It seems to be due to the limitation of js
