is.Latitude/Longitude

[kurennoy16]

I faced the issue with validating geo coordinates using is pkg.
Code example:

type GeoPosition struct {
	Latitude  float32
	Longitude float32
}

func (g *GeoPosition) Validate() error {
	return validation.ValidateStruct(g,
		validation.Field(&g.Latitude, validation.Required, is.Latitude),
		validation.Field(&g.Longitude, validation.Required, is.Longitude),
	)
}

It returns an error like that: GeoPosition: (Latitude: must be either a string or byte slice.)..
That confuses me a bit. I dug into the issues and found that is pkg only applicable to string/slice byte types.

So what's the way to address Latitude/Longitude validation for float types?
I see only one option - custom validation creation, but that's an inconvenient way to handle that. Any plans to use generics for that?
