pub async fn get_backup(context: &Context, qr: Qr) -> Result<()>Expand description
Contacts a backup provider and receives the backup from it.
This uses a QR code to contact another instance of deltachat which is providing a backup
using the BackupProvider. Once connected it will authenticate using the secrets in
the QR code and retrieve the backup.
This is a long running operation which will return only when completed.
Using Qr as argument is a bit odd as it only accepts specific variant of it. It
does avoid having [iroh_net::NodeAddr] in the primary API however, without
having to revert to untyped bytes.
