| #### Note: this error code is no longer emitted by the compiler. |
| |
| A type with `packed` representation hint has a field with `align` |
| representation hint. |
| |
| Erroneous code example: |
| |
| ```ignore (no longer emitted) |
| #[repr(align(16))] |
| struct Aligned(i32); |
| |
| #[repr(packed)] // error! |
| struct Packed(Aligned); |
| ``` |
| |
| Just like you cannot have both `align` and `packed` representation hints on the |
| same type, a `packed` type cannot contain another type with the `align` |
| representation hint. However, you can do the opposite: |
| |
| ``` |
| #[repr(packed)] |
| struct Packed(i32); |
| |
| #[repr(align(16))] // ok! |
| struct Aligned(Packed); |
| ``` |
