Trait Implementations

impl Debug for IndirectFn

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

Formats the value using the given formatter.

impl Function for IndirectFn

Converts text into a reference and returns the referenced value or range.

INDIRECT lets formulas build references dynamically from strings such as "A1" or "Sheet2!B3:C5".

Remarks

• a1_style defaults to TRUE (A1 style parsing).
• a1_style=FALSE (R1C1 parsing) is currently not implemented and returns #N/IMPL!.
• Invalid or unresolved references return #REF!.
• The function is volatile because target references can change without direct dependency links.

Examples

title: "Resolve a direct cell reference"
grid:
  A1: 99
formula: '=INDIRECT("A1")'
expected: 99

title: "Resolve a range and aggregate it"
grid:
  A1: 5
  A2: 7
  A3: 9
formula: '=SUM(INDIRECT("A1:A3"))'
expected: 21

faq:
  - q: "What happens if a1_style is FALSE?"
    a: "R1C1 parsing is not implemented here yet, so INDIRECT(...,FALSE) returns #N/IMPL!."
  - q: "How are bad reference strings reported?"
    a: "If the text cannot be parsed or resolved to a valid reference, INDIRECT returns #REF!."

fn caps(&self) -> FnCaps

Capability flags for this function

fn name(&self) -> &'static str

fn min_args(&self) -> usize

fn arg_schema(&self) -> &'static [ArgSchema]

fn eval_reference<'a, 'b, 'c>( &self, args: &'c [ArgumentHandle<'a, 'b>], _ctx: &dyn FunctionContext<'b>, ) -> Option<Result<ReferenceType, ExcelError>>

Optional reference result path. Only called by the interpreter/engine when the callsite expects a reference (e.g., range combinators, by-ref argument positions, or spill sources).

fn eval<'a, 'b, 'c>( &self, args: &'c [ArgumentHandle<'a, 'b>], ctx: &dyn FunctionContext<'b>, ) -> Result<CalcValue<'b>, ExcelError>

The unified evaluation path.

fn namespace(&self) -> &'static str

fn variadic(&self) -> bool

fn volatile(&self) -> bool

fn aliases(&self) -> &'static [&'static str]

Optional list of additional alias names (case-insensitive) that should resolve to this function. Default: empty slice. Implementors can override to expose legacy names. Returned slice must have ’static lifetime (typically a static array reference).

fn function_salt(&self) -> u64

fn dispatch<'a, 'b, 'c>( &self, args: &'c [ArgumentHandle<'a, 'b>], ctx: &dyn FunctionContext<'b>, ) -> Result<CalcValue<'b>, ExcelError>

Dispatch to the unified evaluation path with automatic argument validation.
