| around the <code>Inner</code> value.</p> |
| <p>This allows safely copy transmuting between the <code>Inner</code> type and the |
| <code>TransparentWrapper</code> type. Functions like <code>wrap_{}</code> convert from the inner |
| type to the wrapper type and <code>peel_{}</code> functions do the inverse conversion |
| from the wrapper type to the inner type. We deliberately do not call the |
| wrapper-removing methods “unwrap” because at this point that word is too |
| strongly tied to the Option/ Result methods.</p> |
| <h2 id="safety"><a href="#safety">Safety</a></h2> |
| <p>The safety contract of <code>TransparentWrapper</code> is relatively simple:</p> |
| <p>For a given <code>Wrapper</code> which implements <code>TransparentWrapper<Inner></code>:</p> |
| <ol> |
| <li> |
| <p><code>Wrapper</code> must be a wrapper around <code>Inner</code> with an identical data |
| representations. This either means that it must be a |
| <code>#[repr(transparent)]</code> struct which contains a either a field of type |
| <code>Inner</code> (or a field of some other transparent wrapper for <code>Inner</code>) as |
| the only non-ZST field.</p> |
| </li> |
| <li> |
| <p>Any fields <em>other</em> than the <code>Inner</code> field must be trivially constructable |
| ZSTs, for example <code>PhantomData</code>, <code>PhantomPinned</code>, etc. (When deriving |
| <code>TransparentWrapper</code> on a type with ZST fields, the ZST fields must be |
| <a href="trait.Zeroable.html" title="Zeroable"><code>Zeroable</code></a>).</p> |
| </li> |
| <li> |
| <p>The <code>Wrapper</code> may not impose additional alignment requirements over |
| <code>Inner</code>.</p> |
| <ul> |
| <li>Note: this is currently guaranteed by <code>repr(transparent)</code>, but there |
| have been discussions of lifting it, so it’s stated here explicitly.</li> |
| </ul> |
| </li> |
| <li> |
| <p>All functions on <code>TransparentWrapper</code> <strong>may not</strong> be overridden.</p> |
| </li> |
| </ol> |
| <h3 id="caveats"><a href="#caveats">Caveats</a></h3> |
| <p>If the wrapper imposes additional constraints upon the inner type which are |
| required for safety, it’s responsible for ensuring those still hold – this |
| generally requires preventing access to instances of the inner type, as |
| implementing <code>TransparentWrapper<U> for T</code> means anybody can call |
| <code>T::cast_ref(any_instance_of_u)</code>.</p> |
| <p>For example, it would be invalid to implement TransparentWrapper for <code>str</code> |
| to implement <code>TransparentWrapper</code> around <code>[u8]</code> because of this.</p> |
