Error code E0745

The address of temporary value was taken.

Erroneous code example:

#![allow(unused)] fn main() { fn temp_address() { let ptr = &raw const 2; // error! } }

In this example, 2 is destroyed right after the assignment, which means that ptr now points to an unavailable location.

To avoid this error, first bind the temporary to a named local variable:

#![allow(unused)] fn main() { fn temp_address() { let val = 2; let ptr = &raw const val; // ok! } }
