Struct Document 

pub struct Document { /* private fields */ }

One text, its language, and its current tree.

Implementations

impl Document

pub fn new(tag: &str, source: impl Into<String>) -> Option<Self>

Parse source as the language tag names.

pub fn with_lang(lang: &'static Lang, source: impl Into<String>) -> Option<Self>

pub fn source(&self) -> &str

The text as of the last edit.

pub fn edit( &mut self, range: Range<usize>, new_end: usize, source: &str, ) -> Vec<Range<usize>>

range of the text held became the new_end - range.start bytes of source that start at range.start, and source is the whole text now. Reparses from the old tree and answers the byte ranges of source whose spans may have changed.

pub fn spans(&self) -> Vec<(Range<usize>, HighlightKind)>

Spans over the whole text, in document order.

pub fn spans_in( &self, range: Range<usize>, ) -> Vec<(Range<usize>, HighlightKind)>

Spans over the part of the text range covers, clipped to it.
