README

        
This module wraps [go-qrcode](github.com/yeqown/go-qrcode)'s [standard writer](https://github.com/yeqown/go-qrcode/tree/main/writer/standard) replacing the call to `os` with [afero](https://github.com/spf13/afero#memory-backed-storage) (A FileSystem Abstraction System for Go) for those of us that don't need to write to an actual file.

Example

qr.go

```go

package main

import (

	"fmt"

	qrcode_memwriter "github.com/kfatehi/go-qrcode-memwriter"

	"github.com/spf13/afero"

	"github.com/yeqown/go-qrcode/v2"

	"github.com/yeqown/go-qrcode/writer/standard"

)

func generate_qr(AppFs afero.Fs, path string, content string) (string, error) {

	qrc, err := qrcode.New(content)

	if err != nil {

		fmt.Printf("could not generate QRCode: %v", err)

		return "", err

	}

	w, err := qrcode_memwriter.New(AppFs, path, standard.WithQRWidth(4))

	if err != nil {

		fmt.Printf("standard.New failed: %v", err)

		return "", err

	}

	if err = qrc.Save(w); err != nil {

		fmt.Printf("could not save image: %v", err)

		return "", err

	}

	return path, nil

}
