Struct TracedReference

#[repr(C)]
pub struct TracedReference<T> { /* private fields */ }

A traced handle without destructor that clears the handle. The embedder needs to ensure that the handle is not accessed once the V8 object has been reclaimed. For more details see BasicTracedReference.

Implementations

impl<T> TracedReference<T>

pub fn empty() -> Self

An empty TracedReference without storage cell.

pub fn new(scope: &mut HandleScope<'_, ()>, data: Local<'_, T>) -> Self

Construct a TracedReference from a Local.

A new storage cell is created pointing to the same object.

pub fn get<'s>(&self, scope: &mut HandleScope<'s, ()>) -> Option<Local<'s, T>>

pub fn reset( &mut self, scope: &mut HandleScope<'_, ()>, data: Option<Local<'_, T>>, )

Always resets the reference. Creates a new reference from other if it is non-empty.
