the destructor of <code>T</code> and free the allocated memory. Since the
way <code>Box</code> allocates and releases memory is unspecified, the

<p>This function is mainly useful for data that lives for the remainder of
the program's life. Dropping the returned reference will cause a memory
leak. If this is not acceptable, the reference should first be wrapped
with the <a href="struct.Box.html#method.from_raw"><code>Box::from_raw</code></a> function producing a <code>Box</code>. This <code>Box</code> can
then be dropped which will properly destroy <code>T</code> and release the
allocated memory.</p>
<p>Note: this is an associated function, which means that you have
to call it as <code>Box::leak(b)</code> instead of <code>b.leak()</code>. This
is so that there is no conflict with a method on the inner type.</p>
