# witer
witer is a wrapper around Go's iter package, designed to simplify and extend its functionality for more convenient iteration handling.
## Usage
### Filter
```golang
import "github.com/hirokisan/witer"
iter := witer.New(slices.Values([]int64{1, 2, 3}))
items := iter.Filter(func(v int64) bool {
return v%2 == 0
}).Collect()
```
```golang
import "github.com/hirokisan/witer"
iter := witer.New2(maps.All(map[int64]string{
0: "a",
1: "b",
2: "c",
}))
items := maps.Collect(iter.Filter(func(k int64, v string) bool {
return k%2 == 0 && v == "a"
}).Iter())
```
### Apply
```golang
import "github.com/hirokisan/witer"
iter := witer.New(slices.Values([]int64{1, 2, 3}))
items := iter.Apply(func(v int64) int64 {
return v * 10
}).Collect()
```
```golang
import "github.com/hirokisan/witer"
iter := witer.New2(maps.All(map[int64]string{
0: "a",
1: "b",
2: "c",
}))
items := maps.Collect(iter.Apply(func(k int64, v string) (int64, string) {
return k * 10, v
}).Iter())
```
