warning: taking a mutable reference to a `const` item
|
|
--> tests/ui-nightly/transmute-mut-const.rs:20:52
|
|
|
|
|
20 | const CONST_CONTEXT: &mut [u8; 2] = transmute_mut!(&mut ARRAY_OF_U8S);
|
|
| ^^^^^^^^^^^^^^^^^
|
|
|
|
|
= note: each usage of a `const` item creates a new temporary
|
|
= note: the mutable reference will refer to this temporary, not the original `const` item
|
|
note: `const` item defined here

|
--> tests/ui-nightly/transmute-mut-const.rs:17:1
|
|
|
|
|
17 | const ARRAY_OF_U8S: [u8; 2] = [0u8; 2];
|
|
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
= note: `#[warn(const_item_mutation)]` on by default
|
|
|
|
error[E0015]: cannot call non-const method `Wrap::<&mut [u8; 2], &mut [u8; 2]>::transmute_mut` in constants

20 | const CONST_CONTEXT: &mut [u8; 2] = transmute_mut!(&mut ARRAY_OF_U8S);
|
|
| ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
|
|
|
|
|
= note: calls in constants are limited to constant functions, tuple structs and tuple variants
|
|
= note: this error originates in the macro `transmute_mut` (in Nightly builds, run with -Z macro-backtrace for more info)
