### <span id="Unwrap">Unwrap</span>
<p>Unwrap if err is nil then it returns a valid value. If err is not nil, Unwrap panics with err.</p>

<b>Signature:</b>

```go
func Unwrap[T any](val T, err error) T
```
<b>Example:</b>

```go
package main

import (
    "fmt"
    "github.com/duke-git/lancet/v2/xerror"
)

func main() {
	result1 := xerror.Unwrap(strconv.Atoi("42"))
	fmt.Println(result1)

	_, err := strconv.Atoi("4o2")
	defer func() {
		v := recover()
		result2 := reflect.DeepEqual(err.Error(), v.(*strconv.NumError).Error())
		fmt.Println(result2)
	}()

	xerror.Unwrap(strconv.Atoi("4o2"))

	// Output:
	// 42
	// true
}
```
