[−][src]Struct rusty_v8::ContextScope

pub struct ContextScope<'s, P> { /* fields omitted */ }

Stack-allocated class which sets the execution context for all operations executed within a local scope. After entering a context, all code compiled and run is compiled and run in this context.

Implementations

impl<'s, P: NewContextScope<'s>> ContextScope<'s, P>[src]

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

Methods from Deref<Target = HandleScope<'p>>

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.
