Function core::mem::align_of_val

pub fn align_of_val<T: ?Sized>(val: &T) -> usize

This is supported on non-crate feature miri-test-libstd or test or doctest only.

Returns the ABI-required minimum alignment of the type of the value that val points to.

Every reference to a value of the type T must be a multiple of this number.

Examples

use std::mem;

assert_eq!(4, mem::align_of_val(&5i32));
