   A port of Java's ConcurrentHashMap to Rust

   

   Recently I learned about the hyaline reclamation scheme that seize uses. Mentioning since it may interest you:flurry, a concurrent HashMap, recently switched from crossbeam-epoch (based on epoch GC) to seize.

6. librseq

   5 2 70 7.3 C

   Library for Restartable Sequences

   

   The epoch GC library I've used before was a Google-internal C++ one. It noticeably improved my software's tail latency over rwlocks. The unique thing about it is that it was basically zero-cost over a plain non-atomic pointer. It used Linux restartable sequences (aka rseq) to take advantage of synchronization operations Linux does on each context switch, rather than adding new atomics. I'm not aware of any open source synchronization libraries that do the same thing, but there's nothing stopping someone from writing one. rseq kernel support has been in mainline since Linux 4.18.
