Provided Methods

fn open<'a>(&'a self, isolate: &mut Isolate) -> &'a Self::Data

Returns a reference to the V8 heap object that this handle represents. The handle does not get cloned, nor is it converted to a Local handle.

Panics

This function panics in the following situations:

• The handle is not hosted by the specified Isolate.
• The Isolate that hosts this handle has been disposed.

unsafe fn get_unchecked(&self) -> &Self::Data

Reads the inner value contained in this handle, without verifying that the this handle is hosted by the currently active Isolate.

Safety

Using a V8 heap object with another Isolate than the Isolate that hosts it is not permitted under any circumstance. Doing so leads to undefined behavior, likely a crash.

Panics

This function panics if the Isolate that hosts the handle has been disposed.

Object Safety

This trait is not object safe.
