Struct rusty_v8::PropertyCallbackArguments [−][src]
pub struct PropertyCallbackArguments<'s> { /* fields omitted */ }Implementations
Returns the receiver. In many cases, this is the object on which the
property access was intercepted. When using
Reflect.get, Function.prototype.call, or similar functions, it is the
object passed in as receiver or thisArg.
