This crate makes it possible to store objects containing dynamic fields either compactly in consecutive memory or using traditional heap pointers.

Bread-and-butter datastructures are offered, they feature:

  • transparent access semantics, independent of currently used storage
  • automatic spill from exhausted compact storage to heap storage
  • recursive re-compaction

This is used in Kay for:

  • Storing actor state compactly in one place for cache coherency and easy persistence
  • Sending complex, dynamically-sized messages over boundaries such as actors, threads and the network
