Crate wifi_qr_code

Wifi QR codes are a way to encode wifi connection information and credentials into a QR code so that it can be scanned. They are supported via the latest Android and iOS phones, as well as other platforms.

It is important to take into account that QR codes do not provide any security mechanisms that would prevent someone from just reading the code and recovering the password for the network. Android requires that you re-authenticate before it will display the QR code on the screen to make sure the user is allowed to share that information, for example.

Structs

• QrCodeEcc
  The error correction level in a QR Code symbol.
