Distribution of [Uber H3geo](https://h3geo.org/) cells by nodes 

Prerequisites

-------

[H3-Go requires CGO ](https://github.com/uber/h3-go#prerequisites)

Install

-------

With a correctly configured Go env:

```

go get github.com/mmadfox/go-h3geo-dist

```

Examples

--------

```go

package main

import (

	"fmt"

	h3geodist "github.com/mmadfox/go-h3geo-dist"

	"github.com/uber/h3-go/v3"

)

func main() {

	level := h3geodist.Level1

	h3dist, err := h3geodist.New(level)

	if err != nil {

		panic(err)

	}

	_ = h3dist.Add("127.0.0.1")

	_ = h3dist.Add("127.0.0.2")

	_ = h3dist.Add("127.0.0.3")

	// iterate over all cells level one

	h3geodist.Iter(level, func(index uint, cell h3.H3Index) {

		// find a node by h3geo cell

		dcell, ok := h3dist.Lookup(cell)

		fmt.Printf("h3dist.Lookup: cell=%v, host=%s, found=%v\n", cell, dcell.Host, ok)

	})

	h3dist.LookupMany([]h3.H3Index{

		h3.FromString("821fa7fffffffff"),

		h3.FromString("821f9ffffffffff"),

		h3.FromString("81973ffffffffff"),

		h3.FromString("81f07ffffffffff"),

	}, func(c h3geodist.Cell) bool {

		fmt.Printf("h3dist.LookupMany: cell=%v, host=%s\n", c.H3ID, c.Host)

		return true

	})

	h3dist.Remove("127.0.0.1")

	h3dist.Remove("127.0.0.2")

	h3dist.Remove("127.0.0.3")

}
