error[E0015]: cannot call non-const closure in constant functions
--> $DIR/issue-56164.rs:1:18
|
LL | const fn foo() { (||{})() }
| ^^^^^^^^
|
= note: closures need an RFC before allowed to be called in constant functions
= note: calls in constant functions are limited to constant functions, tuple structs and tuple variants
error: function pointer calls are not allowed in constant functions
--> $DIR/issue-56164.rs:7:5

LL | input()
| ^^^^^^^
error: erroneous constant used
--> $DIR/issue-56164.rs:1:18
|
LL | const fn foo() { (||{})() }
| ^^^^^^ referenced constant has errors
|
= note: `#[deny(const_err)]` on by default
= warning: this was previously accepted by the compiler but is being phased out; it will become a hard error in a future release!
= note: for more information, see issue #71800 <https://github.com/rust-lang/rust/issues/71800>
error: aborting due to 3 previous errors
