Struct DefaultFunctionContext 

pub struct DefaultFunctionContext<'a> {
    pub base: &'a dyn EvaluationContext,
    pub current: Option<CellRef>,
}

Default adapter that wraps an EvaluationContext and provides the narrow FunctionContext.

Fields

base: &'a dyn EvaluationContext

current: Option<CellRef>

Implementations

impl<'a> DefaultFunctionContext<'a>

pub fn new(base: &'a dyn EvaluationContext, current: Option<CellRef>) -> Self

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

Resolve a reference into a RangeView using the underlying engine context.

fn arrow_fastpath_enabled(&self) -> bool

Feature gate: enable Arrow fast paths in builtins (e.g., SUMIFS)

fn date_system(&self) -> DateSystem

Workbook date system selection (1900 vs 1904).

fn get_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. Returns None if not supported by the underlying context.

fn get_or_build_mask(&self, _key: &str) -> Option<DenseMask>

Get a pre-built criteria mask if available (Phase 3) Returns None if not warmed up or not available

fn rng_for_current(&self, fn_salt: u64) -> SmallRng

Deterministic RNG seeded for the current evaluation site and function salt.
