Error code E0013

Note: this error code is no longer emitted by the compiler

Static and const variables can refer to other const variables. But a const variable cannot refer to a static variable.

Erroneous code example:

#![allow(unused)] fn main() { static X: i32 = 42; const Y: i32 = X; }

In this example, Y cannot refer to X. To fix this, the value can be extracted as a const and then used:

#![allow(unused)] fn main() { const A: i32 = 42; static X: i32 = A; const Y: i32 = A; }
