Struct BufferContent 

pub struct BufferContent { /* private fields */ }

Implementations

impl BufferContent

pub fn new() -> Self

pub fn version(&self) -> u64

Returns the current version number. Incremented on each edit.

pub fn text(&self) -> String

pub fn len_bytes(&self) -> usize

pub fn len_chars(&self) -> usize

pub fn is_empty(&self) -> bool

pub fn byte_at(&self, offset: usize) -> Option<u8>

Get a single byte at the given offset, if it exists.

pub fn rope(&self) -> &Rope

pub fn tree(&self) -> Option<&MarkdownTree>

pub fn lines(&self) -> &[LineMarkers]

pub fn render_snapshot(&mut self) -> RenderSnapshot

Create a render snapshot for efficient virtualized rendering. Ensures code highlight cache is valid before creating the snapshot. All Rc clones are O(1). LineMarkers are computed lazily per-line.

pub fn inline_styles_for_range(&self, range: &Range<usize>) -> Vec<StyledRegion>

Get inline styles that overlap with a byte range. Uses binary search for efficient O(log n) lookup.

pub fn byte_to_line(&self, byte_offset: usize) -> usize

pub fn line_to_byte(&self, line: usize) -> usize

pub fn line_count(&self) -> usize

pub fn is_line_empty(&self, line_idx: usize) -> bool

Returns true if the line has no content (only markers or whitespace). Code fences are always considered content.

pub fn line_byte_range(&self, line_idx: usize) -> Range<usize>

pub fn slice_cow(&self, range: Range<usize>) -> Cow<'_, str>

Get a byte slice from the rope, borrowing if possible. Returns a Cow that borrows if the slice fits in one chunk, allocates otherwise.

pub fn code_highlights_for_range( &mut self, range: Range<usize>, ) -> Vec<HighlightSpan>

pub fn normalize_document(&mut self) -> bool

Normalize the document. Currently does nothing - we preserve the file as-is.

Trait Implementations

impl Default for BufferContent

fn default() -> Self

Returns the “default value” for a type.
