Fields

references: HashSet<ObjectReference>

The table of reference objects for the current semantics. We add references to this table by add_candidate(). After scanning this table, a reference in the table should either stay in the table (if the referent is alive) or go to enqueued_reference (if the referent is dead and cleared). Note that this table should not have duplicate entries, otherwise we will scan the duplicates multiple times, and that may lead to incorrect results.

enqueued_references: Vec<ObjectReference>

References whose referents are cleared during this GC. We add references to this table during scanning, and we pop from this table during the enqueue work at the end of GC.

nursery_index: usize

Index into the references table for the start of nursery objects
