error[E0015]: cannot call non-const fn `Y::foo` in statics
--> $DIR/issue-16538.rs:14:23
|
LL | static foo: &Y::X = &*Y::foo(Y::x as *const Y::X);
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
= note: calls in statics are limited to constant functions, tuple structs and tuple variants
= note: consider wrapping this expression in `Lazy::new(|| ...)` from the `once_cell` crate: https://crates.io/crates/once_cell
error[E0133]: use of extern static is unsafe and requires unsafe function or block
--> $DIR/issue-16538.rs:14:30
|
LL | static foo: &Y::X = &*Y::foo(Y::x as *const Y::X);
| ^^^^ use of extern static
|
= note: extern statics are not controlled by the Rust type system: invalid data, aliasing violations or data races will cause undefined behavior
error[E0133]: dereference of raw pointer is unsafe and requires unsafe function or block
--> $DIR/issue-16538.rs:14:21
|
LL | static foo: &Y::X = &*Y::foo(Y::x as *const Y::X);
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ dereference of raw pointer
|
= note: raw pointers may be null, dangling or unaligned; they can violate aliasing rules and cause data races: all of these are undefined behavior
error: aborting due to 3 previous errors
