error[E0133]: dereference of raw pointer is unsafe and requires unsafe function or block
|
|
--> $DIR/issue-16538.rs:14:22
|
|
|
|
|
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[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[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
