pub fn highlighted_html_for_string(
    s: &str,
    ss: &SyntaxSet,
    syntax: &SyntaxReference,
    theme: &Theme,
) -> Result<String, Error>Expand description
Convenience method that combines start_highlighted_html_snippet, styled_line_to_highlighted_html
and HighlightLines from syntect::easy to create a full highlighted HTML snippet for
a string (which can contain many lines).
Note that the syntax passed in must be from a SyntaxSet compiled for newline characters.
This is easy to get with SyntaxSet::load_defaults_newlines(). (Note: this was different before v3.0)
