## Generics

some generics-based helper functions for working with slices and sets (go 1.18+)

Usage:

```go

package main

import (

	"fmt"

	"github.com/goiste/generics/sets"

	"github.com/goiste/generics/slices"

)

func main() {

	x := []int{1, 2, 3, 4, 5}

	fmt.Println(slices.Reverse(x)) // [5 4 3 2 1]

	f := slices.Convert[int, float64](x)

	fmt.Printf("%T\n", f[0])   // float64

	fmt.Println(slices.Min(f)) // 1

	fmt.Println(slices.Max(f)) // 5

	fmt.Println(slices.Sum(f)) // 15

	

	f = []float64{0.000001, 0.02, 0.300000003}

	formatted := slices.Format(f, "%.2f")

	fmt.Println(formatted) // [0.00 0.02 0.30]

	genInt := slices.SequenceGenerator(10, -1)

	fmt.Println(genInt()) // 10

	fmt.Println(genInt()) // 9

	fmt.Println(genInt()) // 8

	// ...

	s := sets.Make[string]("one", "two", "three")

	s.Add("three", "four", "five")

	s.Diff(sets.Make[string]("four", "five"))

	s.Map(func(str string) string {

		return str + "!"

	})

	fmt.Println(s.Has("one!")) // true

	s.Delete("one!")

	fmt.Println(s.Len()) // 2

}

```
