<p>The pointer must be properly aligned. Since it is aligned, a tag can be stored into the unused
|
|
|
|
|
|
least significant bits of the address. More precisely, a tag should be less than <code>(1 << mem::align_of::<T>().trailing_zeros())</code>.</p>
|
|
|
|
|
|
<p>Any method that loads the pointer must be passed a reference to a <a href="struct.Guard.html"><code>Guard</code></a>.</p>

|
|
<p>This is similar to the "acquire" ordering, except that an ordering is
|
|
|
|
|
|
only guaranteed with operations that "depend on" the result of the load.
|
|
|
|
|
|
However consume loads are usually much faster than acquire loads on
|
|
|
|
|
|
architectures with a weak memory model since they don't require memory
|
|
|
|
|
|
fence instructions.</p>
|
|
|
|
|
|
<p>The exact definition of "depend on" is a bit vague, but it works as you
|
|
|
|
|
|
would expect in practice since a lot of software, especially the Linux
|
|
|
|
|
|
kernel, rely on this behavior.</p>
