Function core::mem::align_of

pub const fn align_of<T>() -> usize

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

Returns the ABI-required minimum alignment of a type.

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

This is the alignment used for struct fields. It may be smaller than the preferred alignment.

Examples

use std::mem;

assert_eq!(4, mem::align_of::<i32>());
