error[E0308]: mismatched types
--> $DIR/issue-51154.rs:2:30
|
LL | fn foo<F: FnMut()>() {
| - expected this type parameter
LL | let _: Box<F> = Box::new(|| ());
| -------- ^^^^^ expected type parameter `F`, found closure
| |
| arguments to this function are incorrect
|
= note: expected type parameter `F`
found closure `{closure@$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`
note: associated function defined here
--> $SRC_DIR/alloc/src/boxed.rs:LL:COL
error: aborting due to 1 previous error
