Struct rusty_v8::scope::Entered

#[repr(C)]
pub struct Entered<'s, S, P = ()> { /* fields omitted */ }

A wrapper around the an instantiated and entered scope object.

Methods

impl<'s, S, P> Entered<'s, S, P> where
    Self: InIsolate, 

pub fn isolate(&mut self) -> &mut Isolate

impl<'s, 'p: 's, S, P> Entered<'s, S, P> where
    Self: ToLocal<'p>, 

pub fn get_current_context(&mut self) -> Option<Local<'p, Context>>

Returns the context of the currently running JavaScript, or the context on the top of the stack if no JavaScript is running.

pub fn get_entered_or_microtask_context(&mut self) -> Option<Local<'p, Context>>

Returns either the last context entered through V8's C++ API, or the context of the currently running microtask while processing microtasks. If a context is entered while executing a microtask, that context is returned.

impl<'s, 'p: 's, S, P> Entered<'s, S, P> where
    Self: EscapeLocal<'s, 'p>, 

pub fn escape<T>(&mut self, local: Local<T>) -> Local<'p, T>

Pushes the value into the previous scope and returns a handle to it. Cannot be called twice.
