Expand description

Error representing a problem when collecting the recipient devices for the room key, during an encryption operation.

Variants§

§

VerifiedUserHasUnsignedDevice(BTreeMap<OwnedUserId, Vec<OwnedDeviceId>>)

One or more verified users has one or more unsigned devices.

Happens only with CollectStrategy::DeviceBasedStrategy when error_on_verified_user_problem is true.

In order to resolve this, the caller can set the trust level of the affected devices to LocalTrust::Ignored or LocalTrust::BlackListed (see Device::set_local_trust), and then retry the encryption operation.

§

VerifiedUserChangedIdentity(Vec<OwnedUserId>)

One or more users was previously verified, but they have changed their identity.

Happens only with CollectStrategy::DeviceBasedStrategy when error_on_verified_user_problem is true, or with CollectStrategy::IdentityBasedStrategy.

In order to resolve this, the user can:

The caller can then retry the encryption operation.

§

CrossSigningNotSetup

Cross-signing has not been configured on our own identity.

Happens only with CollectStrategy::IdentityBasedStrategy. (Cross-signing is required for encryption when using IdentityBasedStrategy.) Apps should detect this condition and prevent sending in the UI rather than waiting for this error to be returned when encrypting.

§

SendingFromUnverifiedDevice

The current device has not been cross-signed by our own identity.

Happens only with CollectStrategy::IdentityBasedStrategy. (Cross-signing is required for encryption when using IdentityBasedStrategy.) Apps should detect this condition and prevent sending in the UI rather than waiting for this error to be returned when encrypting.
