Here's a simple example demonstrating how to use the opt package:
Example
package main
import (
"fmt"
"github.com/WinPooh32/opt"
)
func main() {
var v opt.T[int]
v = opt.Wrap(1)
if v.Set() {
fmt.Println(v.Value())
}
}

package main
import (
"fmt"
"github.com/WinPooh32/opt"
)
func main() {
o1 := opt.Wrap(1)
if v, ok := opt.Unwrap(o1); ok {
fmt.Println(v)
}
o2 := opt.Wrap(2)
if o2.Set() {
fmt.Println(o2.Value())
}
fmt.Println(opt.Less(o1, o2))
fmt.Println(opt.Compare(o1, o2))
