Iterate, Compare, Filter, Map, etc... collection (arrays, slices, maps and custom types) functions!
func main() {
s := []int{0, 1, 2, 3, 4, 5}
iter := collfunc.Iterate[int](s)
for v, ok := iter(); ok; v, ok = iter() {
fmt.Println(v)
}
}Output:
0
1
2
3
4
5
Zip:
func main() {
first := []int{0, 2, 4, 6}
second := []int{1, 3, 5, 7}
fmt.Println(collfunc.ToSlice[int](collfunc.Zip[int](first, second)))
}Output:
[0, 1, 2, 3, 4, 5, 6, 7]
Support for custom collections:
type customIterable int
func (ci customIterable) Iterator() func() (int, bool) {
i := 0
return func() (int, bool) {
if i < int(ci) {
i++
return i - 1, true
}
return 0, false
}
}
func main() {
var ci customIterable = 5
if collfunc.Compare[int](ci, []int{0, 1, 2, 3, 4}) != 0 {
panic(":(")
}
}
