[−][src]Struct rusty_v8::EscapableHandleScope

pub struct EscapableHandleScope<'s, 'e: 's, C = Context> { /* fields omitted */ }

A HandleScope which first allocates a handle in the current scope which will be later filled with the escape value.

Implementations

impl<'s, 'e: 's> EscapableHandleScope<'s, 'e>[src]

pub fn new<P: NewEscapableHandleScope<'s, 'e>>(param: &'s mut P) -> P::NewScope[src]

impl<'s, 'e: 's, C> EscapableHandleScope<'s, 'e, C>[src]

pub fn escape<T>(&mut self, value: Local<T>) -> Local<'e, T> where
    Local<'l, T>: Into<Local<'l, Data>>, [src]

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

Methods from Deref<Target = HandleScope<'s, ()>>

pub fn get_current_context(&self) -> Local<'s, Context>[src]

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(&self) -> Local<'s, Context>[src]

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.

pub fn throw_exception(&mut self, exception: Local<Value>) -> Local<'s, Value>[src]

Schedules an exception to be thrown when returning to JavaScript. When an exception has been scheduled it is illegal to invoke any JavaScript operation; the caller must return immediately and only after the exception has been handled does it become legal to invoke JavaScript operations.

This function always returns the undefined value.
