<h1 id="bits">Bits<a class="headerlink" href="#bits" title="Permanent link">&para;</a></h1>
<p>The bits package is included in Vapor by default and provides a convenient API for working with bytes.</p>
<h2 id="typealias">Typealias<a class="headerlink" href="#typealias" title="Permanent link">&para;</a></h2>
<p>The bits package provides two type-aliases for bytes.</p>
<div class="codehilite"><pre><span></span><span class="kd">typealias</span> <span class="n">Byte</span> <span class="p">=</span> <span class="nb">UInt8</span>
<span class="kd">typealias</span> <span class="n">Bytes</span> <span class="p">=</span> <span class="p">[</span><span class="n">Byte</span><span class="p">]</span>
</pre></div>
<h2 id="bytesconvertible">BytesConvertible<a class="headerlink" href="#bytesconvertible" title="Permanent link">&para;</a></h2>
<p>It's quite often that we want to convert objects to and from byte arrays when we're working. The BytesConvertible helps define objects that have these capabilities. This is implemented already on most objects in Vapor that can/should be converted to and from byte arrays.</p>
<div class="codehilite"><pre><span></span><span class="kd">let</span> <span class="nv">hello</span> <span class="p">=</span> <span class="nb">String</span><span class="p">(</span><span class="n">bytes</span><span class="p">:</span> <span class="p">[</span><span class="mi">72</span><span class="p">,</span> <span class="mi">101</span><span class="p">,</span> <span class="mi">108</span><span class="p">,</span> <span class="mi">108</span><span class="p">,</span> <span class="mi">111</span><span class="p">])</span>
<span class="kd">let</span> <span class="nv">bytes</span> <span class="p">=</span> <span class="n">hello</span><span class="p">.</span><span class="n">makeBytes</span><span class="p">()</span>
</pre></div>
<h2 id="string">String<a class="headerlink" href="#string" title="Permanent link">&para;</a></h2>
<p>Converting from bytes to string using the UTF-8 encoding is easy.</p>
<div class="codehilite"><pre><span></span><span class="kd">let</span> <span class="nv">bytes</span> <span class="p">=</span> <span class="s">&quot;hello&quot;</span><span class="p">.</span><span class="n">makeBytes</span><span class="p">()</span>
<span class="kd">let</span> <span class="nv">string</span> <span class="p">=</span> <span class="n">bytes</span><span class="p">.</span><span class="n">makeString</span><span class="p">()</span>
<span class="bp">print</span><span class="p">(</span><span class="n">string</span><span class="p">)</span> <span class="c1">// &quot;hello&quot;</span>
</pre></div>
<h2 id="byte">Byte<a class="headerlink" href="#byte" title="Permanent link">&para;</a></h2>
<p>The upper and lowercase latin alphabet and some additional control characters are statically typed on the <code>Byte</code>.</p>
<div class="codehilite"><pre><span></span><span class="kd">let</span> <span class="nv">bytes</span><span class="p">:</span> <span class="n">Bytes</span> <span class="p">=</span> <span class="p">[.</span><span class="n">h</span><span class="p">,</span> <span class="p">.</span><span class="n">e</span><span class="p">,</span> <span class="p">.</span><span class="n">l</span><span class="p">,</span> <span class="p">.</span><span class="n">l</span><span class="p">,</span> <span class="p">.</span><span class="n">o</span><span class="p">]</span>
<span class="bp">print</span><span class="p">(</span><span class="n">bytes</span><span class="p">.</span><span class="n">makeString</span><span class="p">())</span> <span class="c1">// &quot;hello&quot;</span>
</pre></div>
<p>This makes byte manipulation and comparison easy and is useful for building things like parsers and serializers.</p>
<div class="codehilite"><pre><span></span><span class="kd">let</span> <span class="nv">byte</span><span class="p">:</span> <span class="n">Byte</span> <span class="p">=</span> <span class="mi">65</span>
<span class="k">if</span> <span class="n">byte</span> <span class="p">==</span> <span class="p">.</span><span class="n">A</span> <span class="p">{</span>
<span class="bp">print</span><span class="p">(</span><span class="s">&quot;found A!&quot;</span><span class="p">)</span>
<span class="p">}</span>
