Kool is a helper library for creating k8s operators.

We use generics! No more FooInformer, BarInformer or BazInformer, just use kool.Informer!

So as Lister and Client.

// Using code-generator or kubebuilder:

var fooInformer FooInformer
var barInformer BarInformer
var bazInformer BazInformer

// Using kool:

import "github.com/FlyingOnion/kool"

var fooInformer kool.Informer[Foo]
var barInformer kool.Informer[Bar]
var bazInformer kool.Informer[Baz]

We provide koolbuilder to generate operator boilerplate online. You don't need to install any code generator binaries.
