Function highlight_with_theme 

Source 
pub fn highlight_with_theme<'a, It>(
    events: It,
    theme: &str,
) -> Result<Vec<Event<'a>>, Error>
where
    It: Iterator<Item = Event<'a>>,
Expand description

Apply syntax highlighting to pulldown-cmark events using the specified theme.

Take an iterator over pulldown-cmark’s events, and (on success) return a new iterator where code blocks have been turned into HTML text blocks with syntax highlighting.

It might be time-consuming to call this method in a hot loop: in that situation you might want to use a PulldownHighlighter object instead.
