This function is only useful within a code block render hook.
Given the context passed into a code block render hook, `transform.HighlightCodeBlock` returns a `HighlightResult` object with two methods.
.Wrapped
: (`template.HTML`) Returns highlighted code wrapped in `<div>`, `<pre>`, and `<code>` elements. This is identical to the value returned by the transform.Highlight function.
.Inner
: (`template.HTML`) Returns highlighted code without any wrapping elements, allowing you to create your own wrapper.
```go-html-template
{{ $result := transform.HighlightCodeBlock . }}
{{ $result.Wrapped }}
```
To override the default [highlighting options]:
```go-html-template
{{ $opts := merge .Options (dict "linenos" true) }}
{{ $result := transform.HighlightCodeBlock . $opts }}
{{ $result.Wrapped }}
```
