Distributed epoch-based memory reclamation

Build Status Latest version Documentation License Rust 1.36+

Many concurrent lock-free data structures require an additional minimal (also lock-free) garbage collector, which determines, when a removed value can be safely de-allocated. This can not be determined statically, since many threads could potentially still access previously created references to the removed value. This crate provides a simple and (mostly) safe interface for interacting with the DEBRA [1] memory reclamation scheme.
