Trait implemented by a plugin function. This trait should not be used directly.

Use the #[export_module] and #[export_fn] procedural attributes instead.

Required methods

fn call(
    &self,
    context: NativeCallContext<'_, '_, '_, '_>,
    args: &mut FnCallArgs<'_>
) -> Result<Dynamic, Box<EvalAltResult>>

Call the plugin function with the arguments provided.

fn is_method_call(&self) -> bool

Is this plugin function a method?

fn is_variadic(&self) -> bool

Is this plugin function variadic?
