|
||
<p>When implementing a custom input type, it is possible to use directly the
|
||
default implementation: If the input type implements <code>InputLength</code>, <code>InputIter</code>,
|
||
<code>InputTake</code> and <code>Clone</code>, you can implement <code>UnspecializedInput</code> and get
|
||
a default version of <code>InputTakeAtPosition</code> and <code>Compare</code>.</p>
|
||
<p>For performance reasons, you might want to write a custom implementation of
|
||
<code>InputTakeAtPosition</code> (like the one for <code>&[u8]</code>).</p>
