- titzer 1y agoOne way is that the writer thread prepares a completely new copy of the object in a private area and then either compare-and-swaps a pointer to it, or executes a store with a store-store barrier (depending on details of the STM system around it).
- codedokode 1y agoInteresting, it's almost like immutable data structures.
