It's a lifetime problem. The argument of returning_st
does indeed need to be static, for complicated reasons. But that's ok, if you do it like this:
use std::sync::{Arc, Mutex};
let mut captured_callback_wrapper = Arc::new(Mutex::new(CallbackWrapper::default()));
let ccw2 = captured_callback_wrapper.clone();
mock_service.expect_exec().returning_st(move |_request, callback_wrapper| {
*ccw2.lock().unwrap() = callback_wrapper;
()
});

Understood. Thanks for the clarification and solution!
