This crate is an early work in progress. The focus for the moment is concurrency:
Non-blocking data structures. These data structures allow for high
performance, highly-concurrent access, much superior to wrapping with a
Mutex. Ultimately the goal is to include stacks, queues, deques, bags, sets
and maps.
Memory management. Because non-blocking data structures avoid global
synchronization, it is not easy to tell when internal data can be safely
freed. The mem module provides generic, easy to use, and high-performance APIs
for managing memory in these cases.
Synchronization. The standard library provides a few synchronization primitives (locks, semaphores, barriers, etc) but this crate seeks to expand that set to include more advanced/niche primitives, as well as userspace alternatives.
Scoped thread API. Finally, the crate provides a "scoped" thread API, making it possible to spawn threads that share stack data with their parents.
To use Crossbeam, add this to your Cargo.toml:
toml
[dependencies]
crossbeam = "0.2.5"
For examples of what Crossbeam is capable of, see the documentation.
