<p>For writing <a href="sus-num-u32.html"><code>u32</code></a> literals.</p>
<p>Un-qualified integer literals are 32 bits large (the size of <code>int</code>) and
signed values, unless a literal suffix modifies them, such as with <code>_u32</code>
which creates an unsigned 32-bit value. This is the same as the <code>u</code> suffix
except that it forces a safe numeric type instead of a primitive value when
this is needed (such as for templates or member function access).</p>
<p>Values out of range for <a href="sus-num-u32.html"><code>u32</code></a> will fail to compile.</p>
