Well optimized ring buffer library in rust

[anshulpandey0606]

Hello everyone,

I am looking for a ring buffer library in rust with the following specs:

1. Highly efficient with enqueue and dequeue operations, it would be nice to have bulk enqueue and dequeue support
2. Support for MPMC
3. Producers and consumers could be on different threads
4. The size should be fixed so that it could be allocated on the heap

Any suggestions on good options available?

The size should be fixed so that it could be allocated on the heap

I don't get this criterion; the heap is perfectly suited for allocating dynamically-sized values.

Anyway, there is VecDeque in std, which you can wrap in an Arc<Mutex<_>>. Wouldn't that work for you?

Two popular options are:

• crossbeam_queue::ArrayQueue

• concurrent_queue::ConcurrentQueue in particular using its bounded constructor

While it's been quite a while since last development, I have never been able to find a faster and more versatile one than multiqueue
