Struct Highlighter 

pub struct Highlighter { /* private fields */ }

Parses and highlights one language.

Implementations

impl Highlighter

pub fn new(language: Language) -> Option<Self>

Build a highlighter, or None if the grammar and its queries disagree — a mismatch between the grammar crate and its query file is a packaging problem, and an editor that refuses to open a file over it would be worse than one that shows it unhighlighted.

pub fn highlight(&mut self, text: &str) -> Vec<Span>

Highlight text.

Returns spans in char offsets, non-overlapping and in document order. On any parse failure the answer is “no highlighting” rather than an error: unhighlighted code is perfectly editable, and half-coloured code from a partial parse is not better.
