Struct v8::Global

source ·
pub struct Global<T> { /* private fields */ }
Expand description

An object reference that is independent of any handle scope. Where a Local handle only lives as long as the HandleScope in which it was allocated, a global handle remains valid until it is explicitly disposed using reset().

A global handle contains a reference to a storage cell within the V8 engine which holds an object value and which is updated by the garbage collector whenever the object is moved.

Implementations§

Construct a new Global from an existing Handle.

Consume this Global and return the underlying raw pointer.

The returned raw pointer must be converted back into a Global by using Global::from_raw, otherwise the V8 value referenced by this global handle will be pinned on the V8 heap permanently and never get garbage collected.

Converts a raw pointer created with Global::into_raw() back to its original Global.

This method tests for self and other values to be equal, and is used by ==.
This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
