Struct DisplayChunk 

pub struct DisplayChunk {
    pub start_source_line: u32,
    pub rows: Arc<[DisplayLine]>,
    pub version: MatrixVersion,
}

Contiguous range of display rows covering a slice of the buffer. Same invariants as CellChunk: rows sorted ascending by source_line, folded lines absent (row count is post-fold), start_source_line is the first source line the chunk’s [start, start + chunk_size) logical range could contain.

Fields

start_source_line: u32

rows: Arc<[DisplayLine]>

version: MatrixVersion

Implementations

impl DisplayChunk

pub fn new( start_source_line: u32, rows: impl Into<Arc<[DisplayLine]>>, version: MatrixVersion, ) -> Self

pub fn empty(start_source_line: u32, version: MatrixVersion) -> Self

pub fn row_count(&self) -> u32

pub fn is_empty(&self) -> bool

pub fn row_at_source_line(&self, target: u32) -> Option<&DisplayLine>

Row whose source_line == target, or None if folded / outside the chunk. Binary search (rows are sorted).

pub fn shifted_by(&self, line_delta: i32, new_version: MatrixVersion) -> Self

Clone-with-shifted-line: start_source_line and every row’s source_line shift by line_delta (saturating at 0); payload Arcs shared. new_version stamps the result.

Trait Implementations

impl Clone for DisplayChunk

fn clone(&self) -> DisplayChunk

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for DisplayChunk

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
