<p>A reference represents a borrow of some owned value. You can get one by using the <code>&amp;</code> or <code>&amp;mut</code>
operators on a value, or by using a <code>ref</code> or <code>ref mut</code> pattern.</p>
<p>For those familiar with pointers, a reference is just a pointer that is assumed to not be null.
In fact, <code>Option&lt;&amp;T&gt;</code> has the same memory representation as a nullable pointer, and can be
passed across FFI boundaries as such.</p>
<p>In most cases, references can be used much like the original value. Field access, method
calling, and indexing work the same (save for mutability rules, of course). In addition, the
comparison operators transparently defer to the referent's implementation, allowing references
to be compared the same as owned values.</p>
<p>References have a lifetime attached to them, which represents the scope for which the borrow is
valid. A lifetime is said to &quot;outlive&quot; another one if its representative scope is as long or
longer than the other. The <code>'static</code> lifetime is the longest lifetime, which represents the
total life of the program. For example, string literals have a <code>'static</code> lifetime because the
text data is embedded into the binary of the program, rather than in an allocation that needs
to be dynamically managed.</p>
<p><code>&amp;mut T</code> references can be freely coerced into <code>&amp;T</code> references with the same referent type, and
references with longer lifetimes can be freely coerced into references with shorter ones.</p>
<p>For more information on how to use references, see <a href="../book/second-edition/ch04-02-references-and-borrowing.html">the book's section on &quot;References and
Borrowing&quot;</a>.</p>
<p>The following traits are implemented for all <code>&amp;T</code>, regardless of the type of its referent:</p>
<ul>
<li><a href="marker/trait.Copy.html"><code>Copy</code></a></li>
<li><a href="clone/trait.Clone.html"><code>Clone</code></a> (Note that this will not defer to <code>T</code>'s <code>Clone</code> implementation if it exists!)</li>
<li><a href="ops/trait.Deref.html"><code>Deref</code></a></li>
<li><a href="borrow/trait.Borrow.html"><code>Borrow</code></a></li>
<li><a href="fmt/trait.Pointer.html"><code>Pointer</code></a></li>
</ul>
<p><code>&amp;mut T</code> references get all of the above except <code>Copy</code> and <code>Clone</code> (to prevent creating
multiple simultaneous mutable borrows), plus the following, regardless of the type of its
referent:</p>
<ul>
<li><a href="ops/trait.DerefMut.html"><code>DerefMut</code></a></li>
<li><a href="borrow/trait.BorrowMut.html"><code>BorrowMut</code></a></li>
</ul>
<p>The following traits are implemented on <code>&amp;T</code> references if the underlying <code>T</code> also implements
that trait:</p>
<ul>
<li>All the traits in <a href="fmt/index.html"><code>std::fmt</code></a> except <a href="fmt/trait.Pointer.html"><code>Pointer</code></a> and <a href="fmt/trait.Write.html"><code>fmt::Write</code></a></li>
<li><a href="cmp/trait.PartialOrd.html"><code>PartialOrd</code></a></li>
<li><a href="cmp/trait.Ord.html"><code>Ord</code></a></li>
<li><a href="cmp/trait.PartialEq.html"><code>PartialEq</code></a></li>
<li><a href="cmp/trait.Eq.html"><code>Eq</code></a></li>
<li><a href="convert/trait.AsRef.html"><code>AsRef</code></a></li>
<li><a href="ops/trait.Fn.html"><code>Fn</code></a> (in addition, <code>&amp;T</code> references get <a href="ops/trait.FnMut.html"><code>FnMut</code></a> and <a href="ops/trait.FnOnce.html"><code>FnOnce</code></a> if <code>T: Fn</code>)</li>
<li><a href="hash/trait.Hash.html"><code>Hash</code></a></li>
<li><a href="net/trait.ToSocketAddrs.html"><code>ToSocketAddrs</code></a></li>
</ul>
<p><code>&amp;mut T</code> references get all of the above except <code>ToSocketAddrs</code>, plus the following, if <code>T</code>
implements that trait:</p>
<ul>
<li><a href="convert/trait.AsMut.html"><code>AsMut</code></a></li>
<li><a href="ops/trait.FnMut.html"><code>FnMut</code></a> (in addition, <code>&amp;mut T</code> references get <a href="ops/trait.FnOnce.html"><code>FnOnce</code></a> if <code>T: FnMut</code>)</li>
<li><a href="fmt/trait.Write.html"><code>fmt::Write</code></a></li>
<li><a href="iter/trait.Iterator.html"><code>Iterator</code></a></li>
<li><a href="iter/trait.DoubleEndedIterator.html"><code>DoubleEndedIterator</code></a></li>
<li><a href="iter/trait.ExactSizeIterator.html"><code>ExactSizeIterator</code></a></li>
<li><a href="iter/trait.FusedIterator.html"><code>FusedIterator</code></a></li>
<li><a href="iter/trait.TrustedLen.html"><code>TrustedLen</code></a></li>
<li><a href="marker/trait.Send.html"><code>Send</code></a> (note that <code>&amp;T</code> references only get <code>Send</code> if <code>T: Sync</code>)</li>
<li><a href="io/trait.Write.html"><code>io::Write</code></a></li>
<li><a href="io/trait.Read.html"><code>Read</code></a></li>
<li><a href="io/trait.Seek.html"><code>Seek</code></a></li>
<li><a href="io/trait.BufRead.html"><code>BufRead</code></a></li>
</ul>
<p>Note that due to method call deref coercion, simply calling a trait method will act like they
work on references as well as they do on owned values! The implementations described here are
meant for generic contexts, where the final type <code>T</code> is a type parameter or otherwise not
locally known.</p>
