Crossbeam Epoch

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 alloc feature is enabled.

Usage

Add this to your Cargo.toml:

[dependencies]
crossbeam-epoch = "0.9"

Compatibility

Crossbeam Epoch supports stable Rust releases going back at least six months, and every time the minimum supported Rust version is increased, a new minor version is released. Currently, the minimum supported Rust version is 1.36.
