Module highlighter 

This module provides a syntax highlighter for Rust code. It is used by the rustc --explain command.

The syntax highlighter uses rustc_lexer’s tokenize function to parse the Rust code into a Vec of tokens. The highlighter then highlights the tokens in the Vec, and writes the highlighted output to the buffer.
