Module roots 

Root scanning infrastructure for the GC.

The Trace trait is implemented by types that contain GC-managed pointers. During the mark phase, the GC calls trace() on root objects to discover all reachable heap pointers.

Traits

Trace

Trait for types that can be traced by the GC.

Functions

trace_heap_slot

Trace a raw u64 that may be a heap pointer (for ValueSlot).

trace_nanboxed_bits

Trace a NaN-boxed u64 value: if it’s heap-tagged, yield the raw pointer.

Type Aliases

TraceCallback

Callback type for tracing — accepts raw pointers to GC-managed objects.
