Java at 30: The Genius Behind the Code That Changed Tech

One very common queue implementation you can use to implement actors is the crossbeam-deque. It's work-stealing in nature, works in multi-threaded environments and has no locks. The implementation is quite simple to follow:

Note that the mpsc queue in the rust stdlib is also a clone of crossbeam and therefore also lockless.

I can't find any references to a "crossbeam dequeue" outside of Rust sources. Is this a neologism for a "very common" pattern, or just very common in Rust?

crossbeam is a package name. It would be like googling “Nokogiri XML” and only getting Ruby results.

The generic name is just Deque. https://en.wikipedia.org/wiki/Double-ended_queue
