Static rustc_lint::builtin::UNSAFE_CODE

static UNSAFE_CODE: &Lint

The unsafe_code lint catches usage of unsafe code and other potentially unsound constructs like no_mangle, export_name, and link_section.

Example

#![deny(unsafe_code)]
fn main() {
    unsafe {

    }
}

#[no_mangle]
fn func_0() { }

#[export_name = "exported_symbol_name"]
pub fn name_in_rust() { }

#[no_mangle]
#[link_section = ".example_section"]
pub static VAR1: u32 = 1;

Explanation

This lint is intended to restrict the usage of unsafe blocks and other constructs (including, but not limited to no_mangle, link_section and export_name attributes) wrong usage of which causes undefined behavior.
