error[E0277]: the trait bound `&mut FastApiCallbackOptions<'_>: Deserialize<'_>` is not satisfied
  --> tests/compile_fail/unsupported.rs:17:1

17 | #[op(fast)]
   | ^^^^^^^^^^^ the trait `Deserialize<'_>` is not implemented for `&mut FastApiCallbackOptions<'_>`

   = help: the following other types implement trait `Deserialize<'de>`:
             &'a Path
             &'a [u8]
             &'a str
             ()
             (T0, T1)
             (T0, T1, T2)
             (T0, T1, T2, T3)
             (T0, T1, T2, T3, T4)
           and 143 others
note: required by a bound in `from_v8`
