This tool can be useful for writing a tests. If you want change private field in struct from imported libraries than it can help you.

## Example

```go

package main

import (

	"strings"

	

	"github.com/dedalqq/omg.testingtools"

)

func TestSomeCase(t *testing.T) {

	buffer := strings.Builder{}

	

	testingtools.SetPrivateValue(&buffer, "buf", []byte("data in strings buffer"))

}

```

## How it works

This function finding needs field via `reflect` then get pointer from field address via `unsafe.Pointer` and write value via variable with the same address as original struct field.
