Scala Coroutines is a library-level extension for the Scala programming language that introduces first-class coroutines.
Coroutines are a language abstraction that generalizes subroutines (i.e. procedures, methods or functions). Unlike a subroutine, which is invoked once and executes until it completed, a coroutine can pause execution and yield control back to the caller, or another coroutine. The caller can then resume the coroutine when appropriate. Coroutines have a number of use cases, including but not limited to:
- data structure iterators
- event-driven code without the inversion of control
- cooperative multitasking
- concurrency frameworks such as actors, async-await and dataflow networks
- expressing asynchrony, and better composition of asynchronous systems
- capturing continuations
- expressing backtracking algorithms
- AI agents such as behavior trees
To learn how to use coroutines, please see the Scala Coroutines Guide in the documentation section.
