FindIndexOf	findindexof	it/find.go#L112	it	find	func FindIndexOf[T any](collection iter.Seq[T], predicate func(item T) bool) (T, int, bool)	https://go.dev/play/p/6TeNM7kg-r	it#find#findindexof	core#slice#findindexof it#find#find it#find#findlastindexof	50

Searches for an element based on a predicate and returns the element, its index, and true if found. Returns zero value, -1, and false if not found.

Examples:

seq := func(yield func(int) bool) {
    _ = yield(10)
    _ = yield(20)
    _ = yield(30)
    _ = yield(40)
}
found, index, ok := it.FindIndexOf(seq, func(x int) bool {
    return x > 25
})
// found == 30, index == 2, ok == true

seq := func(yield func(string) bool) {
    _ = yield("apple")
    _ = yield("banana")
    _ = yield("cherry")
}
found, index, ok := it.FindIndexOf(seq, func(s string) bool {
    return s == "orange"
})
// found == "", index == -1, ok == false
