| An incompatible cast was attempted. |
| |
| Erroneous code example: |
| |
| ```compile_fail,E0606 |
| let x = &0u8; // Here, `x` is a `&u8`. |
| let y: u32 = x as u32; // error: casting `&u8` as `u32` is invalid |
| ``` |
| |
| When casting, keep in mind that only primitive types can be cast into each |
| other. Example: |
| |
| ``` |
| let x = &0u8; |
| let y: u32 = *x as u32; // We dereference it first and then cast it. |
| ``` |
| |
| For more information about casts, take a look at the Type cast section in |
| [The Reference Book][1]. |
