ref(jsonrpc): Getting backup provider QR code now blocks#4198
Merged
Conversation
This changes the JSON-RPC APIs to get a QR code from the backup provider to block. It means once you have a (blocking) call to provide_backup() you can call get_backup_qr() or get_backup_qr_svg() and they will block until the QR code is available. Calling get_backup_qr() or get_backup_qr_svg() when there is no backup provider will immediately error.

I've jumped through some more hoops in order to get this state entirely in the JSON-RPC crate instead of fudging it into the Context as it was before. I think this is neater, but did involve some effort to get it to work. I hope you don't hate the result. |
