Trait FinalizerEntry 

pub trait FinalizerEntry: Clone {
    // Required methods
    fn identity(&self) -> usize;
    fn age(&self) -> GcAge;
    fn is_finalized(&self) -> bool;
    fn set_finalized(&self, finalized: bool);

    // Provided method
    fn heap_ptr(&self) -> Option<NonNull<GcBox<dyn Trace>>> { ... }
}

Minimal metadata a finalizable VM object must expose for collector-owned finalizer-list bookkeeping.

Required Methods

fn identity(&self) -> usize

fn age(&self) -> GcAge

fn is_finalized(&self) -> bool

fn set_finalized(&self, finalized: bool)

Provided Methods

fn heap_ptr(&self) -> Option<NonNull<GcBox<dyn Trace>>>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety".
