pub trait JsFnOutput<M>: Send + 'static {
    // Required method
    fn into_js_fn_output(self) -> Result<JsValue, JsError>;
}

A value a host function can return: either a plain value convertible Into<JsValue>, or a Result thereof with an error convertible Into<JsError> (thrown inside the script).

The M parameter is an inference marker; ignore it.

Convert into the raw host function output.

In older versions of Rust, dyn compatibility was called "object safety".
