nftnl/src/expr/verdict.rs line 67 at r1 (raw file):

    unsafe fn to_immediate_expr(&self, immediate_const: i32) -> *mut sys::nftnl_expr {
        let expr = try_alloc!(unsafe {
            sys::nftnl_expr_alloc(b"immediate\0" as *const _ as *const c_char)

⛏️ This could be replaced with

c"immediate".as_ptr()

which is kind of goated, ngl

Edit: I saw that you already made this refactor elsewhere after writing this ⛏️ xd

Code quote:

b"immediate\0" as *const _ as *const c_char)
