1/// Macro to wrap closures with `send_wrapper::SendWrapper`.
2///
3/// ## Usage
4///
5/// ```
6/// # use sendwrap_fn::sendwrap_fn;
7///
8/// let wrapped = sendwrap_fn!(move |a: i32, b: i32| { /* do stuff */ });
9/// ```
10///
11/// For closures that implement only `FnOnce`:
12///
13/// ```
14/// # use sendwrap_fn::sendwrap_fn;
15///
16/// let wrapped = sendwrap_fn!(once move || { /* do stuff */ });
17/// ```
