static UNPREDICTABLE_FUNCTION_POINTER_COMPARISONS: &Lint
Expand description
The unpredictable_function_pointer_comparisons
lint checks comparison
of function pointer as the operands.
§Example
fn a() {}
fn b() {}
let f: fn() = a;
let g: fn() = b;
let _ = f == g;
{{produces}}
§Explanation
Function pointers comparisons do not produce meaningful result since they are never guaranteed to be unique and could vary between different code generation units. Furthermore, different functions could have the same address after being merged together.
