pub static FUNCTION_CASTS_AS_INTEGER: &Lint

The function_casts_as_integer lint detects cases where a function item is cast to an integer.

let x = foo as usize;

Explanation

When casting a function item to an integer, it implicitly creates a function pointer that will in turn be cast to an integer. By making it explicit, it improves readability of the code and prevents bugs.
