Epoch-based garbage collection

Crossbeam Epoch

Build Status License Cargo Documentation Rust 1.28+ chat

This crate provides epoch-based garbage collection for building concurrent data structures.

When a thread removes an object from a concurrent data structure, other threads may be still using pointers to it at the same time, so it cannot be destroyed immediately. Epoch-based GC is an efficient mechanism for deferring destruction of shared objects until no pointers to them can exist.

Everything in this crate except the global GC can be used in no_std environments, provided that features alloc and nightly are enabled.


Add this to your Cargo.toml:

crossbeam-epoch = "0.8"

Next, add this to your crate:

extern crate crossbeam_epoch as epoch;


The minimum supported Rust version is 1.28. Any change to this is considered a breaking change.
