## Example

```rust

use struct_pad::{Pad, PadU0, PadU8, PadU16, PadU32};

struct Example {

    field1: u64,

    field2: u8,

    // Padding fields

    pad1: PadU8,

    #[cfg(target_pointer_width = "16")]

    pad2: PadU0,

    #[cfg(not(target_pointer_width = "16"))]

    pad2: PadU16,

    #[cfg(target_pointer_width = "64")]

    pad3: PadU32,

    #[cfg(not(target_pointer_width = "64"))]

    pad3: PadU0,

 }

impl Example {

    const fn new(field1: u64, field2: u8) -> Self {

        Self {

            field1,

            field2,

            pad1: Pad::VALUE,

            pad2: Pad::VALUE,

            pad3: Pad::VALUE,

        }

    }

}

```
