Enum CollectStrategy

pub enum CollectStrategy {
    DeviceBasedStrategy {
        only_allow_trusted_devices: bool,
        error_on_verified_user_problem: bool,
    },
    IdentityBasedStrategy,
}

Strategy to collect the devices that should receive room keys for the current discussion.

Variants

DeviceBasedStrategy

Device based sharing strategy.

Fields

only_allow_trusted_devices: bool

If true, devices that are not trusted will be excluded from the conversation. A device is trusted if any of the following is true: - It was manually marked as trusted. - It was marked as verified via interactive verification. - It is signed by its owner identity, and this identity has been trusted via interactive verification. - It is the current own device of the user.

error_on_verified_user_problem: bool

If true, and a verified user has an unsigned device, key sharing will fail with a SessionRecipientCollectionError::VerifiedUserHasUnsignedDevice.

If true, and a verified user has replaced their identity, key sharing will fail with a SessionRecipientCollectionError::VerifiedUserChangedIdentity.

Otherwise, keys are shared with unsigned devices as normal.

Once the problematic devices are blacklisted or whitelisted the caller can retry to share a second time.

IdentityBasedStrategy

Share based on identity. Only distribute to devices signed by their owner. If a user has no published identity he will not receive any room keys.
