impl ScalarFunction for RepeatFunction
Source§fn info(&self) -> FunctionInfo
fn info(&self) -> FunctionInfo
Get function information
Source§fn evaluate(&self, args: &[Value]) -> Result<Value>
fn evaluate(&self, args: &[Value]) -> Result<Value>
Evaluate the function with the given arguments
Source§fn clone_box(&self) -> Box<dyn ScalarFunction>
fn clone_box(&self) -> Box<dyn ScalarFunction>
Clone the function into a new instance
Source§fn native_fn1(&self) -> Option<NativeFn1>
fn native_fn1(&self) -> Option<NativeFn1>
Optional: Return a direct function pointer for single-arg functions.
When Some, compiler emits direct call (no dynamic dispatch).
Default is None (uses evaluate() with dynamic dispatch).
