Wikipedia: Coroutine
The coro module provides cooperative coroutines. A coroutine suspends at each yield call and resumes when iterated or when .resume() is called.
fmt := import("fmt")
coro := import("coro")gen := coro.new(func(yield) {
yield(1)
yield(2)
yield(3)
})for _, v in gen {
fmt.println(v)
}countdown := coro.new(func(yield) {
for i := 5; i > 0; i-- {
yield(i)
}
})
v, ok := countdown.resume()
fmt.printf("%v %v\n", v, ok)
v, ok = countdown.resume()
fmt.printf("%v %v\n", v, ok)try it
