|
||
|
||
<p>FIXME (pnkfelix): Ideally we would just reuse <code>Box<T></code> instead of
|
||
introducing a separate <code>IntermediateBox<T></code>; but then you hit
|
||
issues when you e.g. attempt to destructure an instance of <code>Box</code>,
|
||
since it is a lang item and so it gets special handling by the
|
||
compiler. Easier just to make this parallel type for now.</p>
|
||
|
||
<p>FIXME (pnkfelix): Currently the <code>box</code> protocol only supports
|
||
creating instances of sized types. This IntermediateBox is
|
||
designed to be forward-compatible with a future protocol that
|
||
supports creating instances of unsized types; that is why the type
|
||
parameter has the <code>?Sized</code> generalization marker, and is also why
|
||
this carries an explicit size. However, it probably does not need
|
||
to carry the explicit alignment; that is just a work-around for
|
||
the fact that the <code>align_of</code> intrinsic currently requires the
|
||
input type to be Sized (which I do not think is strictly
|
||
necessary).</p>

<h2>Search Tricks</h2>
|
||
|
||
<p>
|
||
Prefix searches with a type followed by a colon (e.g.
|
||
<code>fn:</code>) to restrict the search to a given type.
|
||
</p>
|
||
|
||
<p>
|
||
Accepted types are: <code>fn</code>, <code>mod</code>,
|
||
<code>struct</code>, <code>enum</code>,
|
||
<code>trait</code>, <code>type</code>, <code>macro</code>,
|
||
and <code>const</code>.
|
||
</p>
|
||
|
||
<p>
|
||
Search functions by type signature (e.g.
|
||
<code>vec -> usize</code> or <code>* -> vec</code>)
