error[E0308]: mismatched types
--> $DIR/fn-ptr.rs:11:21
|
LL | #[target_feature(enable = "sse2")]
| ---------------------------------- `#[target_feature]` added here
...
LL | let foo: fn() = foo;
| ---- ^^^ cannot coerce functions with `#[target_feature]` to safe function pointers
| |
| expected due to this
|
= note: expected fn pointer `fn()`
found fn item `fn() {foo}`
= note: fn items are distinct from fn pointers
= note: functions with `#[target_feature]` can only be coerced to `unsafe` function pointers
= note: when the arguments and return types match, functions can be coerced to function pointers
help: consider casting to a fn pointer
|
LL | let foo: fn() = foo as fn();
| ~~~~~~~~~~~
error: aborting due to previous error
