Crossbeam crate for concurrency

https://crates.io/crates/crossbeam

The Rust crossbeam crate provides low-level primitives for concurrent programming, such as locks, channels, and memory fences. These primitives are useful when fine-grained synchronization is required, or when working with non-standard concurrency patterns.

The crossbeam crate makes concurrent programming easier by providing:

• Atomic types: such as AtomicBool, AtomicI32, and AtomicUsize, which can be used to perform atomic operations on shared variables without the need for locks. This allows for efficient and safe concurrent access to shared data.

• Locks: such as Mutex, RwLock, and Semaphore, which can be used to protect shared resources from concurrent access. These locks are highly efficient and can be used in both single-threaded and multi-threaded contexts.

• Channels: such as unbounded(), bounded(), and select(), which can be used to communicate between threads. These channels are highly efficient and can be used to implement many common concurrency patterns, such as producer-consumer and pipeline processing.

• Memory fences: such as atomic::fence(), which can be used to enforce ordering constraints on memory accesses. This is useful when working with non-standard concurrency patterns or when fine-grained synchronization is required.

Overall, the crossbeam crate provides a powerful set of low-level primitives for concurrent programming in Rust, allowing developers to build complex and efficient concurrent applications with ease.
