<p>Letting the foreign library borrow pointers from the Rust side often
|
|||
|
|
requires having a temporary variable of an intermediate type (e.g. <code>CString</code>).
|
|||
|
|
A <code>Stash</code> contains the temporary storage and a pointer into it that
|
|||
|
|
is valid for the lifetime of the <code>Stash</code>. As the lifetime of the <code>Stash</code> returned
|
|||
|
|
from <code>to_glib_none</code> is at least the enclosing statement, you can avoid explicitly
|
|||
|
|
binding the stash in most cases and just take the pointer out of it:</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>)
|
|||
|
|
