----
-
-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 }}
-```
