Available on crate features e2e-encryption and qrcode only.

Expand description

An error for the different failure modes that can happen during the validation of a scanned QR code.

Variants

`Store(CryptoStoreError)`

An IO error inside the crypto store happened during the validation of the QR code scan.

`KeyMismatch`

Fields

expected: String

The expected ed25519 key.

found: String

The ed25519 key that we got.

A key mismatch happened during the validation of the QR code scan.

`MissingCrossSigningIdentity(OwnedUserId)`

One of the users that is participating in this verification doesn’t have a valid cross signing identity.

`MissingDeviceKeys(OwnedUserId, OwnedDeviceId)`

The device of the user that is participating in this verification doesn’t have a valid device key.

`FlowIdMismatch`

Fields

expected: String

The expected verification flow id.

found: String

The verification flow id that we instead got.

The ID uniquely identifying this verification flow didn’t match to the one that has been scanned.
