Enum BuiltInFn 

pub enum BuiltInFn {
    Native(NativeFn),
    Plugin(Box<dyn Fn(&mut EvalContext, JsValue, Vec<JsValue>) -> Result<JsValue, JErrorType> + Send + Sync>),
    Script(Rc<FunctionData>),
}

Built-in function - either compiled-in or plugin-provided.

Variants

Native(NativeFn)

Direct function pointer - zero overhead for compiled-in functions.

Plugin(Box<dyn Fn(&mut EvalContext, JsValue, Vec<JsValue>) -> Result<JsValue, JErrorType> + Send + Sync>)

Plugin-provided function - small vtable indirection cost.

Script(Rc<FunctionData>)

JavaScript implementation - interpreted at runtime.

Implementations

impl BuiltInFn

pub fn call( &self, ctx: &mut EvalContext, this: JsValue, args: Vec<JsValue>, ) -> Result<JsValue, JErrorType>

Execute this built-in function.
