Struct ArgumentHandle 

pub struct ArgumentHandle<'a, 'b> { /* private fields */ }

Implementations

impl<'a, 'b> ArgumentHandle<'a, 'b>

pub fn value(&self) -> Result<CowValue<'_>, ExcelError>

pub fn range(&self) -> Result<Box<dyn Range>, ExcelError>

pub fn range_view(&self) -> Result<RangeView<'_>, ExcelError>

Resolve as a RangeView (Phase 2 API). Only supports reference arguments.

pub fn value_or_range(&self) -> Result<EvaluatedArg<'_>, ExcelError>

pub fn lazy_values_owned( &'a self, ) -> Result<Box<dyn Iterator<Item = LiteralValue> + 'a>, ExcelError>

Lazily iterate values for this argument in row-major expansion order.

• Reference: stream via RangeView (row-major)
• Array literal: evaluate each element lazily per cell
• Scalar/other expressions: a single value

pub fn ast(&self) -> &'a ASTNode

pub fn as_reference(&self) -> Result<&'a ReferenceType, ExcelError>

Returns the raw reference from the AST when this argument is a reference. This does not evaluate the reference or materialize values.

pub fn as_reference_or_eval(&self) -> Result<ReferenceType, ExcelError>

Returns a ReferenceType if this argument is a reference or a function that can yield a reference via eval_reference. Materializes no values.

pub fn matches_kind(&self, k: ArgKind) -> Result<bool, ExcelError>
