Struct RangeView 

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

Unified view over a 2D range with efficient traversal utilities. Phase 4: Arrow-only backing.

Implementations

impl<'a> RangeView<'a>

pub fn with_cancel_token(self, token: Option<Arc<AtomicBool>>) -> Self

pub fn sheet(&self) -> &ArrowSheet

pub fn from_owned_rows( rows: Vec<Vec<LiteralValue>>, date_system: DateSystem, ) -> RangeView<'static>

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

pub fn expand_to(&self, rows: usize, cols: usize) -> RangeView<'a>

pub fn sub_view( &self, rs: usize, cs: usize, rows: usize, cols: usize, ) -> RangeView<'a>

pub fn is_empty(&self) -> bool

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 kind_probe(&self) -> RangeKind

pub fn as_1x1(&self) -> Option<LiteralValue>

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

Get a specific cell by row and column index (0-based). Returns Empty for out-of-bounds access.

pub fn iter_row_chunks(&self) -> RowChunkIterator<'_>

Iterate overlapping chunks by row segment.

pub fn for_each_cell( &self, f: &mut dyn FnMut(&LiteralValue) -> Result<(), ExcelError>, ) -> Result<(), ExcelError>

Row-major cell traversal.

pub fn for_each_row( &self, f: &mut dyn FnMut(&[LiteralValue]) -> Result<(), ExcelError>, ) -> Result<(), ExcelError>

Visit each row as a borrowed slice (buffered).

pub fn for_each_col( &self, f: &mut dyn FnMut(&[LiteralValue]) -> Result<(), ExcelError>, ) -> Result<(), ExcelError>

Visit each column as a contiguous slice (buffered).

pub fn get_cell_numeric( &self, row: usize, col: usize, policy: CoercionPolicy, ) -> Option<f64>

Get a numeric value at a specific cell, with coercion. Returns None for empty cells or non-coercible values.

pub fn numbers_chunked( &self, policy: CoercionPolicy, min_chunk: usize, f: &mut dyn FnMut(NumericChunk<'_>) -> Result<(), ExcelError>, ) -> Result<(), ExcelError>

Numeric chunk iteration with coercion policy.

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

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

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

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

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

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

pub fn lowered_text_slices( &self, ) -> impl Iterator<Item = Result<(usize, usize, Vec<Arc<StringArray>>), ExcelError>> + '_

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

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

Typed error-code slices per row-segment.

pub fn type_tags_slices( &self, ) -> impl Iterator<Item = Result<(usize, usize, Vec<Arc<UInt8Array>>), ExcelError>> + '_

Typed type-tag 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.

pub fn slice_numbers( &self, rel_start: usize, len: usize, ) -> Vec<Option<Arc<Float64Array>>>

Slice typed float arrays for a specific row interval (relative to view).

pub fn slice_lowered_text( &self, rel_start: usize, len: usize, ) -> Vec<Option<Arc<StringArray>>>

Slice typed lowered text arrays for a specific row interval (relative to view).
