| <p>This is an unsafe trait, and incorrectly implementing it is undefined |
| behavior.</p> |
| <p>Informally, by implementing it, you’re asserting that <code>C</code> is identical to |
| the integral type <code>C::Int</code>, and that every <code>C</code> falls between <code>C::MIN_VALUE</code> |
| and <code>C::MAX_VALUE</code> exactly once, without any gaps.</p> |
| <p>Precisely, the guarantees you must uphold when implementing <code>Contiguous</code> for |
| some type <code>C</code> are:</p> |
| <ol> |
| <li> |
| <p>The size of <code>C</code> and <code>C::Int</code> must be the same, and neither may be a ZST. |
| (Note: alignment is explicitly allowed to differ)</p> |
| </li> |
| <li> |
| <p><code>C::Int</code> must be a primitive integer, and not a wrapper type. In the |
| future, this may be lifted to include cases where the behavior is |
| identical for a relevant set of traits (Ord, arithmetic, …).</p> |
| </li> |
| <li> |
| <p>All <code>C::Int</code>s which are in the <em>inclusive</em> range between <code>C::MIN_VALUE</code> |
| and <code>C::MAX_VALUE</code> are bitwise identical to unique valid instances of |
| <code>C</code>.</p> |
| </li> |
| <li> |
| <p>There exist no instances of <code>C</code> such that their bitpatterns, when |
| interpreted as instances of <code>C::Int</code>, fall outside of the <code>MAX_VALUE</code> / |
| <code>MIN_VALUE</code> range – It is legal for unsafe code to assume that if it |
| gets a <code>C</code> that implements <code>Contiguous</code>, it is in the appropriate range.</p> |
| </li> |
| <li> |
| <p>Finally, you promise not to provide overridden implementations of |
| <code>Contiguous::from_integer</code> and <code>Contiguous::into_integer</code>.</p> |
| </li> |
| </ol> |
| <p>For clarity, the following rules could be derived from the above, but are |
| listed explicitly:</p> |
| <ul> |
| <li> |
| <p><code>C::MAX_VALUE</code> must be greater or equal to <code>C::MIN_VALUE</code> (therefore, <code>C</code> |
| must be an inhabited type).</p> |
| </li> |
| <li> |
| <p>There exist no two values between <code>MIN_VALUE</code> and <code>MAX_VALUE</code> such that |
| when interpreted as a <code>C</code> they are considered identical (by, say, match).</p> |
| </li> |
| </ul> |

| <p>Contiguous is broadly intended for use with fieldless enums, and for |
| these the correct integer type is easy: The enum should have a |
| <code>#[repr(Int)]</code> or <code>#[repr(C)]</code> attribute, (if it does not, it is |
| <em>unsound</em> to implement <code>Contiguous</code>!).</p> |
| <ul> |
| <li> |
| <p>For <code>#[repr(Int)]</code>, use the listed <code>Int</code>. e.g. <code>#[repr(u8)]</code> should use |
| <code>type Int = u8</code>.</p> |
| </li> |
| <li> |
| <p>For <code>#[repr(C)]</code>, use whichever type the C compiler will use to |
| represent the given enum. This is usually <code>c_int</code> (from <code>std::os::raw</code> |
| or <code>libc</code>), but it’s up to you to make the determination as the |
| implementer of the unsafe trait.</p> |
