Struct zkgroup::api::groups::GroupSendEndorsementsResponse

pub struct GroupSendEndorsementsResponse { /* private fields */ }

The response issued from the group server, containing endorsements for all of a group’s members.

The group server may cache this for a particular group as long as the group membership does not change (being careful of expiration, of course). It is the same for every requesting member.

Implementations

impl GroupSendEndorsementsResponse

pub fn default_expiration(current_time: Timestamp) -> Timestamp

pub fn issue( member_ciphertexts: impl IntoIterator<Item = UuidCiphertext>, key_pair: &GroupSendDerivedKeyPair, randomness: RandomnessBytes, ) -> Self

Issues new endorsements, one for each of member_ciphertexts.

expiration must match the expiration used to derive key_pair;

pub fn expiration(&self) -> Timestamp

Returns the expiration for all endorsements in the response.

pub fn receive_with_service_ids_single_threaded( self, user_ids: impl IntoIterator<Item = ServiceId>, now: Timestamp, group_params: &GroupSecretParams, server_params: &ServerPublicParams, ) -> Result<Vec<ReceivedEndorsement>, ZkGroupVerificationFailure>

Same as [receive_with_service_ids], but without parallelizing the zkgroup-specific parts of the operation.

Only interesting for benchmarking. The zkcredential part of the operation may still be parallelized.

pub fn receive_with_service_ids<T>( self, user_ids: T, now: Timestamp, group_params: &GroupSecretParams, server_params: &ServerPublicParams, ) -> Result<Vec<ReceivedEndorsement>, ZkGroupVerificationFailure>

where T: IntoParallelIterator<Item = ServiceId>, T::Iter: IndexedParallelIterator,

Validates and returns the endorsements issued by the server.

The result will be in the same order as user_ids. user_ids should contain the current user as well.

If you already have the member ciphertexts for the group available, [receive_with_ciphertexts] will be faster than this method.

pub fn receive_with_ciphertexts( self, member_ciphertexts: impl IntoIterator<Item = UuidCiphertext>, now: Timestamp, server_params: &ServerPublicParams, ) -> Result<Vec<ReceivedEndorsement>, ZkGroupVerificationFailure>

Validates and returns the endorsements issued by the server.

The result will be in the same order as member_ciphertexts. member_ciphertexts should contain the current user as well.

If you don’t already have the member ciphertexts for the group available, [receive_with_service_ids] will be faster than computing them separately, using this method, and then throwing the ciphertexts away.
