Struct BitXorFn 

pub struct BitXorFn;

Returns the bitwise exclusive OR of two non-negative integers.

Keeps bits that differ between the two inputs.

Remarks

• Arguments are coerced to numbers and must be whole numbers in the range [0, 2^48).
• Returns #NUM! for negative values, fractional values, or out-of-range values.
• Propagates input errors.

Examples

title: "Highlight differing bits"
formula: "=BITXOR(13,10)"
expected: 7

title: "XOR identical values"
formula: "=BITXOR(5,5)"
expected: 0

    a: "XOR keeps only differing bits; identical operands cancel every bit position."

impl Function for BitXorFn

[formualizer-docgen:schema:start] Name: BITXOR Type: BitXorFn Min args: 2 Max args: 2 Variadic: false Signature: BITXOR(arg1: number@scalar, arg2: number@scalar) Arg schema: arg1{kinds=number,required=true,shape=scalar,by_ref=false,coercion=NumberLenientText,max=None,repeating=None,default=false}; arg2{kinds=number,required=true,shape=scalar,by_ref=false,coercion=NumberLenientText,max=None,repeating=None,default=false} Caps: PURE [formualizer-docgen:schema:end]

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<'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 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.
