//! Epoch-based reclamation.
//!
//! The epoch consensus algorithm and the use of memory barriers and RMW semantics are similar to
//! that of [`crossbeam_epoch`](https://docs.rs/crossbeam-epoch/), however the API set is vastly
//! different, for instance, `unsafe` blocks are not required to read an instance subject to EBR.
