EbrCell - A concurrently readable cell with Ebr
An EbrCell can be used in place of a RwLock. Readers are guaranteed that
the data will not change during the lifetime of the read. Readers do
not block writers, and writers do not block readers. Writers are serialised
same as the write in a RwLock.
This is the Ebr collected implementation.
Ebr is the crossbeam-epoch based reclaim system for async memory
garbage collection. Ebr is faster than Arc,
but long transactions can cause the memory usage to grow very quickly
before a garbage reclaim. This is a space time trade, where you gain
performance at the expense of delaying garbage collection. Holding Ebr
reads for too long may impact garbage collection of other epoch structures
or crossbeam library components.
If you need accurate memory reclaim, use the Arc (CowCell) implementation.
