Trait Implementations

impl Default for TestWorkbook

fn default() -> TestWorkbook

Returns the “default value” for a type.

impl EvaluationContext for TestWorkbook

fn resolve_range_view<'c>( &'c self, reference: &ReferenceType, _current_sheet: &str, ) -> Result<RangeView<'c>, ExcelError>

Resolve a reference into a RangeView with clear bounds. Implementations should resolve un/partially bounded references using used-region.

fn used_rows_for_columns( &self, sheet: &str, start_col: u32, end_col: u32, ) -> Option<(u32, u32)>

Optional: Return the min/max used rows for a set of columns on a sheet. When None, the backend does not provide used-region hints.

fn used_cols_for_rows( &self, sheet: &str, start_row: u32, end_row: u32, ) -> Option<(u32, u32)>

Optional: Return the min/max used columns for a set of rows on a sheet. When None, the backend does not provide used-region hints.

fn sheet_bounds(&self, _sheet: &str) -> Option<(u32, u32)>

Optional: Physical sheet bounds (max rows, max cols) if known.

fn backend_caps(&self) -> BackendCaps

Backend capability advertisement for IO/adapters.

fn thread_pool(&self) -> Option<&Arc<ThreadPool>>

Get access to the shared thread pool for parallel evaluation Returns None if parallel evaluation is disabled or unavailable

fn cancellation_token(&self) -> Option<&AtomicBool>

Optional cancellation token. When Some, long-running operations should periodically abort.

fn chunk_hint(&self) -> Option<usize>

Optional chunk size hint for streaming visitors.

fn locale(&self) -> Locale

Locale provider: invariant by default

fn timezone(&self) -> &TimeZoneSpec

Timezone provider for date/time functions Default: Local (Excel-compatible behavior) Functions should use local timezone when this returns Local

fn volatile_level(&self) -> VolatileLevel

Volatile granularity. Default Always for backwards compatibility.

fn workbook_seed(&self) -> u64

A stable workbook seed for RNG composition.

fn recalc_epoch(&self) -> u64

Recalc epoch that increments on each full recalc when appropriate.

fn data_snapshot_id(&self) -> u64

Monotonic identifier for the current data snapshot; increments on mutation.

fn arrow_fastpath_enabled(&self) -> bool

Feature gate: enable Arrow fast paths in builtins (e.g., SUMIFS). Default is false; engines that wish to enable must override.

fn date_system(&self) -> DateSystem

Workbook date system selection (1900 vs 1904). Defaults to 1900 for compatibility.

fn build_criteria_mask( &self, _view: &ArrowRangeView<'_>, _col_in_view: usize, _pred: &CriteriaPredicate, ) -> Option<Arc<BooleanArray>>

Optional: Build or fetch a cached boolean mask for a criterion over an Arrow-backed view. Implementations should return None if not supported.
