Enum CollectStrategy

pub enum CollectStrategy {
    AllDevices,
    ErrorOnVerifiedUserProblem,
    IdentityBasedStrategy,
    OnlyTrustedDevices,
}

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

Variants

AllDevices

Share with all (unblacklisted) devices.

ErrorOnVerifiedUserProblem

Share with all devices, except errors for verified users cause sharing to fail with an error.

In this strategy, if a verified user has an unsigned device, key sharing will fail with a SessionRecipientCollectionError::VerifiedUserHasUnsignedDevice. If 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.

OnlyTrustedDevices

Only share keys with devices that we “trust”. 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.
