Description
I get an internal compiler error on the input detailed below.
I tried this code:
struct B;
impl B {
fn func(&self) { }
}
fn main() {
let x:&fn(&B) = &B::func;
}
I expected to see this happen: Maybe it should work like let x = &B::func, but I'm guessing that I have some error here. I get an error message when I try a variant of the above;
fn main() {
let y = &B::func;
let z:&fn(&B) = y;
}
This gives me the compile time error:
bug.rs:10:18: 10:19 error: mismatched types:
expected `&fn(&B)`,
found `&fn(&B) {B::func}`
(expected fn pointer,
found fn item) [E0308]
bug.rs:10 let z:&fn(&B) = y;
^
error: aborting due to previous error
Instead, this happened:
error: internal compiler error: unexpected panic
note: the compiler unexpectedly panicked. this is a bug.
note: we would appreciate a bug report: https://github.com/rust-lang/rust/blob/master/CONTRIBUTING.md#bug-reports
