Struct RangeView 

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

Unified view over a 2D range with efficient traversal utilities.

Implementations

impl<'a> RangeView<'a>

pub fn from_borrowed(rows: &'a [Vec<LiteralValue>]) -> Self

pub fn from_arrow(av: ArrowRangeView<'a>) -> Self

pub fn from_graph( graph: &'a DependencyGraph, sheet_id: EngineSheetId, sr: u32, sc: u32, er: u32, ec: u32, ) -> Self

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

pub fn is_empty(&self) -> bool

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

Row-major cell traversal. For borrowable backings, passes borrowed slices/values.

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

Visit each row as a borrowed slice when possible; otherwise uses a reusable buffer per row.

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

Visit each column as a contiguous slice (buffered when needed)

pub fn as_arrow(&self) -> Option<&ArrowRangeView<'a>>

If Arrow-backed, return the underlying ArrowRangeView for vectorized fast paths.

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

impl<'a> RangeView<'a>

pub fn from_hybrid( graph: &'a DependencyGraph, sheet_id: EngineSheetId, sr: u32, sc: u32, arrow: ArrowRangeView<'a>, ) -> Self

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

Formats the value using the given formatter.
