# opt

`opt` is a tiny package that reduces boilerplate for functional options.

Simply decide whether your options can return errors or not, then use the corresponding type.

Without errors:
```go
type Foo struct {
	Bar string
}

func WithBar(b string) opt.Func[Foo] {
	return func(f *Foo) {
			f.Bar = b
    }
}
```

With errors:
```go
type Foo struct {
	Bar string
}

func WithBar(b string) opt.ErrorFunc[Foo] {
	return func(f *Foo) error  {
			f.Bar = b
			return nil
		}
}
```
