Go MergeMaps - Merge two maps

-----------------------------

This [Go (Golang)](http://golang.org/) package provides functions to merge two maps using [reflection](http://golang.org/pkg/reflect/).

[![GoDoc](https://godoc.org/github.com/VojtechVitek/mergemaps?status.png)](https://godoc.org/github.com/VojtechVitek/mergemaps)

[![Travis](https://travis-ci.org/VojtechVitek/mergemaps.svg?branch=master)](https://travis-ci.org/VojtechVitek/mergemaps)

This pkg was merged into [OpenShift 3](https://github.com/openshift/origin) [util pkg](https://github.com/openshift/origin/blob/master/pkg/util/mergemap.go).

Example

-------

```

package main

import (

    map "github.com/VojtechVitek/mergemaps"

)

func main() {

    dst := map[string]string{"foo": "bar"}

    src := map[string]string{"baz": ""}

    // Merge src map into dst map

    err := mergemaps.MergeInto(dst, src, 0 /*flags*/)

    if err != nil {

        fmt.Errorf("Can't merge src into dst: %v", err)

    }

    // Prints map[string]string{"baz":"", "foo":"bar"}

    fmt.Printf("%#v\n", dst)

}

```

See [more examples](examples/examples.go).

Flags

-----

- ErrorOnExistingDstKey

    When set: Return an error if any of the dst keys is already set.

- ErrorOnDifferentDstKeyValue

    When set: Return an error if any of the dst keys is already set to a different value than src key.

- OverwriteDstKey
