thread-local statics cannot be accessed at compile-time

{$kind}s cannot refer to statics

.help = consider extracting the value of the `static` to a `const`, and referring to that

.teach_note = `static` and `const` variables can refer to other `const` variables. A `const` variable, however, cannot refer to a `static` variable.

.teach_help = To fix this, the value can be extracted to a `const` and then used.

const_eval_raw_ptr_to_int =
|
|
pointers cannot be cast to integers during const eval
|

.note = at compile-time, pointers do not have an integer value
|

.note2 = avoiding this restriction via `transmute`, `union`, or raw pointers leads to compile-time undefined behavior

References in statics and constants may only refer to immutable values.\n\n
|

Statics are shared everywhere, and if they refer to mutable data one might violate memory
|

safety since holding multiple mutable references to shared data is not allowed.\n\n
|

If you really want global mutable state, try using static mut or a global UnsafeCell.

allocations are not allowed in {$kind}s

.teach_note =
|
|
The value of statics and constants must be known at compile time, and they live for the entire lifetime of a program. Creating a boxed value allocates memory on the heap at runtime, and therefore cannot be done at compile time.

|
|
.teach_note =
|
|
A constant containing interior mutable data behind a reference can allow you to modify that data.
|
|
This would make multiple uses of a constant to be able to see different values and allow circumventing
|
|
the `Send` and `Sync` requirements for shared mutable data, which is unsound.
|
|
|
|
const_eval_interior_mutability_borrow =
|
|
cannot borrow here, since the borrowed element may contain interior mutability
