This lesson summarizes the concepts covered in this chapter.

We'll cover the following

Chapter summary

  • The call stack enables efficient allocation of local state and simplifies certain algorithms, especially the recursive ones.

  • Fibers enable multiple call stacks per thread instead of the default single call stack per thread.

  • A fiber pauses itself by yielding to its caller, and the caller resumes its fiber by calling it again.

  • Generator presents a fiber as an InputRange.

  • Fibers simplify algorithms that rely heavily on the call stack.

  • Fibers simplify asynchronous input/output operations.

  • Fibers provide cooperative multitasking, which has different trade-offs from preemptive multitasking.
