Struct fedimint_meta_client :: MetaClientModule Copy item path

impl MetaClientModule

pub async fn submit(&self, key: MetaKey, value: MetaValue) -> Result<()>

Submit a meta consensus value

When threshold amount of peers submits the exact same value it becomes a new consensus value.

To “cancel” previous vote, peer can submit a value equal to the current consensus value.

pub async fn get_consensus_value( &self, key: MetaKey ) -> Result<Option<MetaConsensusValue>>

Get the current meta consensus value along with it’s revision

See Self::get_consensus_value_rev to use when checking for updates.

pub async fn get_consensus_value_rev(&self, key: MetaKey) -> Result<Option<u64>>

Get the current meta consensus value revision

Each time a meta consensus value changes, the revision increases, so checking just the revision can save a lot of bandwidth in periodic checks.

pub async fn get_submissions( &self, key: MetaKey ) -> Result<BTreeMap<PeerId, MetaValue>>

Get current submissions to change the meta consensus value.

Upon changing the consensus
