Expand description

Returns the ABI-required minimum alignment of a type in bytes.

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>());
