[−][src]Struct rusty_v8::scope::CallbackScope

pub struct CallbackScope<X = Contained> { /* fields omitted */ }

A CallbackScope can be used to obtain a mutable Isolate reference within a callback that is called by V8 on the thread that already has a Locker on the stack.

Using a CallbackScope in any other situation is unsafe. Also note that CallbackScope should not be used for function and property accessor callbacks; use FunctionCallbackScope and PropertyCallbackScope instead.

A CallbackScope can be created from the following inputs:

  • Local<Context>
  • Local<Message>
  • Local<Object>
  • Local<Promise>
  • Local<SharedArrayBuffer>
  • &PromiseRejectMessage
