# cmp

Package provides comparison for different Go types and a Comparer interface when using structs.

```go

package main

import (

	"fmt"

	"log"

	cmp "github.com/ake-persson/kvstore/cmp"

)

type Car struct {

	Manufacturer string

	Model        string

}

type Cars []*Car

func (c Car) String() string {

	return c.Manufacturer + " " + c.Model

}

func (c Car) Eq(b interface{}) (bool, error) {

	return c.String() == b.(Car).String(), nil

}

func (c Car) Lt(b interface{}) (bool, error) {

	return c.String() < b.(Car).String(), nil

}

func main() {

	cars := Cars{

		&Car{

			Manufacturer: "Audi",

			Model:        "Q3",

		},

		&Car{

			Manufacturer: "Audi",

			Model:        "Q5",

		},

	}

	ok, err := cmp.Eq(cars[0], cars[0])

	if err != nil {

		log.Fatal(err)

	}

	fmt.Printf("ok: %v\n", ok)

	ok, err = cmp.Eq(cars[0], cars[1])

	if err != nil {

		log.Fatal(err)

	}

	fmt.Printf("ok: %v\n", ok)

}

```
