error[E0308]: mismatched types

--> $DIR/issue-51154.rs:2:30

|
|
|

LL | fn foo<F: FnMut()>() {

|
| - this type parameter
|
|
LL | let _: Box<F> = Box::new(|| ());

|
| -------- ^^^^^ expected type parameter `F`, found closure

|

|
|
| arguments to this function are incorrect
|
|
|

= note: expected type parameter `F`
|
|
found closure `[closure@$DIR/issue-51154.rs:2:30: 2:32]`
|
|
= help: every closure has a distinct type and so could not always match the caller-chosen type of parameter `F`
