Struct FindFn 

pub struct FindFn;

Trait Implementations

impl Debug for FindFn

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

Formats the value using the given formatter.

impl Function for FindFn

Returns the 1-based position of one text string inside another.

FIND is case-sensitive and does not interpret wildcard characters.

Remarks

• Search is case-sensitive ("A" and "a" are different).
• start_num is 1-based and must be greater than 0.
• If no match is found, returns #VALUE!.
• Errors in either argument are propagated.

Examples

title: "Case-sensitive match"
formula: '=FIND("World", "Hello World")'
expected: 7

title: "Case mismatch fails"
formula: '=FIND("world", "Hello World")'
expected: "#VALUE!"

  - q: "Do wildcard characters work in FIND?"
    a: "No. FIND treats * and ? as literal characters and matches case-sensitively."

Capability flags for this function

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

fn min_args(&self) -> usize

fn variadic(&self) -> bool

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

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

The unified evaluation path.

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

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 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 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.
