error[E0525]: expected a closure that implements the `AsyncFn` trait, but this closure only implements `AsyncFnMut`

LL | takes_asyncfn(Box::new(async || self.an_async_fn().await));
|
|
| ------------- ---------^^^^^^^^--------------------------
|
|
| | | | |
|
|
| | | | closure is `AsyncFnMut` because it mutates the variable `*self` here
|
|
| | | this closure implements `AsyncFnMut`, not `AsyncFn`
|
|
| | the requirement to implement `AsyncFn` derives from here
|
|
| required by a bound introduced by this call
|
|
|
|
|
= note: required for `Box<{async closure@$DIR/kind-due-to-arg-with-box-wrap.rs:13:32: 13:40}>` to implement `AsyncFn()`

note: required by a bound in `takes_asyncfn`
