You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: html.rs
    path of file: ./repos/syntect/src
    
    the code of the file until where you have to start completion: //! Rendering highlighted code as HTML+CSS
use crate::Error;
use crate::easy::{HighlightFile, HighlightLines};
use crate::escape::Escape;
use crate::highlighting::{Color, FontStyle, Style, Theme};
use crate::parsing::{
    BasicScopeStackOp, ParseState, Scope, Sco
    
    pub fn parse_html_for_line_which_includes_newline(&mut self, line: &str) -> Result<(), Error>{
        let parsed_line = self.parse_state.parse_line(line, self.syntax_set)?;
        let (formatted_line, delta) = line_tokens_to_classed_spans(
            line,
            parsed_line.as_slice(),
            self.style,
            &mut self.scope_stack,
        )?;
        self.open_spans += delta;
        self.html.push_str(formatted_line.as_str());

        Ok(())
    }
