admin_auth: Option<ApiAuth>

Implementations

impl MetaClientModule

pub(crate) fn admin_auth(&self) -> Result<ApiAuth>

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

Trait Implementations

impl ClientModule for MetaClientModule

type Init = MetaClientInit

type Common = MetaModuleTypes

Common module types shared between client and server

type Backup = NoModuleBackup

Data stored in regular backups so that restoring doesn’t have to start from epoch 0

type ModuleStateMachineContext = MetaClientContext

Data and API clients available to state machine transitions of this module

type States = MetaStateMachine

All possible states this client can submit to the executor

fn context(&self) -> Self::ModuleStateMachineContext

fn input_fee( &self, _amount: Amount, _input: &<Self::Common as ModuleCommon>::Input, ) -> Option<Amount>

Returns the fee the processing of this input requires.

fn output_fee( &self, _output: &<Self::Common as ModuleCommon>::Output, ) -> Option<Amount>

Returns the fee the processing of this output requires.

fn supports_being_primary(&self) -> bool

Does this module support being a primary module

fn get_balance<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, _dbtx: &'life1 mut DatabaseTransaction<'life2>, ) -> Pin<Box<dyn Future<Output = Amount> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait,

Returns the balance held by this module and available for funding transactions.

fn handle_cli_command<'life0, 'life1, 'async_trait>( &'life0 self, args: &'life1 [OsString], ) -> Pin<Box<dyn Future<Output = Result<Value>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: 'async_trait,

fn decoder() -> Decoder

fn kind() -> ModuleKind

fn start<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = ()> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: Sync + 'async_trait,

Initialize client.

fn handle_rpc<'life0, 'async_trait>( &'life0 self, _method: String, _request: Value, ) -> Pin<Box<dyn Future<Output = Pin<Box<dyn Stream<Item = Result<Value, Error>> + Send + 'life0>>> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: Sync + 'async_trait,

fn supports_backup(&self) -> bool

fn backup<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Self::Backup, Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: Sync + 'async_trait,

fn create_final_inputs_and_outputs<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, _dbtx: &'life1 mut DatabaseTransaction<'life2>, _operation_id: OperationId, _input_amount: Amount, _output_amount: Amount, ) -> Pin<Box<dyn Future<Output = Result<(Vec<ClientInput<<Self::Common as ModuleCommon>::Input, Self::States>>, Vec<ClientOutput<<Self::Common as ModuleCommon>::Output, Self::States>>), Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, Self: Sync + 'async_trait,

Creates all inputs and outputs necessary to balance the transaction. The function returns an error if and only if the client’s funds are not sufficient to create the inputs necessary to fully fund the transaction.

fn await_primary_module_output<'life0, 'async_trait>( &'life0 self, _operation_id: OperationId, _out_point: OutPoint, ) -> Pin<Box<dyn Future<Output = Result<Amount, Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: Sync + 'async_trait,

Waits for the funds from an output created by Self::create_final_inputs_and_outputs to become available. This function returning typically implies a change in the output of Self::get_balance.

fn subscribe_balance_changes<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Pin<Box<dyn Stream<Item = ()> + Send>>> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: Sync + 'async_trait,

Returns a stream that will output the updated module balance each time it changes.

fn leave<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, _dbtx: &'life1 mut DatabaseTransaction<'life2>, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, 'life2: 'async_trait, Self: Sync + 'async_trait,

Leave the federation

impl Debug for MetaClientModule
