Struct ArrowRangeView 

pub struct ArrowRangeView<'a> { /* private fields */ }

A lightweight view over a rectangular range in an ArrowSheet. Coordinates are 0-based and inclusive.

Implementations

impl<'a> ArrowRangeView<'a>

pub fn start_row(&self) -> usize

Absolute 0-based start row of this view.

pub fn end_row(&self) -> usize

Absolute 0-based end row of this view (inclusive).

pub fn start_col(&self) -> usize

Absolute 0-based start column of this view.

pub fn end_col(&self) -> usize

Absolute 0-based end column of this view (inclusive).

pub fn sheet_name(&self) -> &str

Owning sheet name.

pub fn dims(&self) -> (usize, usize)

pub fn get_cell(&self, row: usize, col: usize) -> LiteralValue

Returns a single cell value relative to this view (row/col 0-based). OOB returns Empty. Phase A: Date/Time/Duration come back as Number with the corresponding TypeTag preserved for higher layers.

pub fn row_chunk_slices(&self) -> Vec<ChunkSlice>

Row-aligned chunk slices within this view. Each item represents a contiguous row segment that lies fully within a single row chunk.

pub fn iter_row_chunks(&'a self) -> impl Iterator<Item = ChunkSlice> + 'a

Convenience iterator over row-aligned chunk slices.

pub fn numbers_slices( &'a self, ) -> impl Iterator<Item = (usize, usize, Vec<Arc<Float64Array>>)> + 'a

Typed numeric slices per row-segment: (row_start, row_len, per-column Float64 arrays)

pub fn booleans_slices( &'a self, ) -> impl Iterator<Item = (usize, usize, Vec<Arc<BooleanArray>>)> + 'a

Typed boolean slices per row-segment, overlay-aware via zip.

pub fn text_slices( &'a self, ) -> impl Iterator<Item = (usize, usize, Vec<ArrayRef>)> + 'a

Text slices per row-segment (erased as ArrayRef for Utf8 today; future Dict/View support).

pub fn errors_slices( &'a self, ) -> impl Iterator<Item = (usize, usize, Vec<Arc<UInt8Array>>)> + 'a

Typed error-code slices per row-segment.

pub fn lowered_text_columns(&self) -> Vec<ArrayRef>

Build per-column concatenated lowered text arrays for this view. Uses per-chunk lowered cache for base text and merges overlays via zip_select.
