Found manual implementation of std::ptr::eq on references RS-W1119
Anti-pattern
Minor
std::ptr::eq can be used to compare &T references (coerced to *const T implicitly)
by their address rather than the values they point to.
Hence, use std::ptr::eq when applicable with &T references.
Bad practice
fn main() {
let a = &[1, 2, 3];
let b = &[1, 2, 3];
assert!(a as *const _ as usize == b as *const _ as usize);
}
Recommended
fn main() {
let a = &[1, 2, 3];
let b = &[1, 2, 3];
assert!(std::ptr::eq(a, b));
}
