Add funding and/or change to the transaction builder as needed, finalize the transaction and submit it to the federation.

Errors

The function will return an error if the operation with given ID already exists.

Panics

The function will panic if the database transaction collides with other and fails with others too often, this should not happen except for excessively concurrent scenarios.

Returns a stream of transaction updates for the given operation id that can later be used to watch for a specific transaction being accepted.

pub fn get_first_instance( &self, module_kind: &ModuleKind, ) -> Option<ModuleInstanceId>

Returns the instance id of the first module of the given kind. The primary module will always be returned before any other modules (which themselves are ordered by their instance ID).

pub async fn root_secret_encoding<T: Decodable>(&self) -> Result<T>

Returns the data from which the client’s root secret is derived (e.g. BIP39 seed phrase struct).

pub async fn await_primary_module_outputs( &self, operation_id: OperationId, outputs: Vec<OutPoint>, ) -> Result<Amount>

Waits for outputs from the primary module to reach its final state.

pub async fn get_config_json(&self) -> JsonClientConfig

Returns the config of the client in JSON format.

Compared to the consensus module format where module configs are binary encoded this format cannot be cryptographically verified but is easier to consume and to some degree human-readable.

pub fn primary_module(&self) -> &DynClientModule

Get the primary module

pub async fn get_balance(&self) -> Amount

Balance available to the client for spending

pub async fn subscribe_balance_changes(&self) -> BoxStream<'static, Amount>

pub async fn set_metadata(&self, metadata: &Metadata)

Set the client Metadata

pub fn has_pending_recoveries(&self) -> bool

pub async fn wait_for_all_recoveries(&self) -> Result<()>

Wait for all module recoveries to finish

This will block until the recovery task is done with recoveries. Returns success if all recovery tasks are complete (success case), or an error if some modules could not complete the recovery at the time.

A bit of a heavy approach.

pub fn subscribe_to_recovery_progress( &self, ) -> impl Stream<Item = (ModuleInstanceId, RecoveryProgress)>

Subscribe to recover progress for all the modules.

This stream can contain duplicate progress for a module. Don’t use this stream for detecting completion of recovery.

pub async fn wait_for_all_active_state_machines(&self) -> Result<()>

pub(crate) fn spawn_module_recoveries_task( &self, recovery_sender: Sender<BTreeMap<ModuleInstanceId, RecoveryProgress>>, module_recoveries: BTreeMap<ModuleInstanceId, Pin<Box<dyn Future<Output = Result<()>> + Send>>>, module_recovery_progress_receivers: BTreeMap<ModuleInstanceId, Receiver<RecoveryProgress>>, )

pub async fn get_peer_url_announcements( &self, ) -> BTreeMap<PeerId, SignedApiAnnouncement>

You likely want to use Client::get_peer_urls. This function returns only the announcements and doesn’t use the config as fallback.

pub async fn get_peer_urls(&self) -> BTreeMap<PeerId, SafeUrl>

Returns a list of guardian API URLs

pub async fn invite_code(&self, peer: PeerId) -> Option<InviteCode>

Create an invite code with the api endpoint of the given peer which can be used to download this client config

pub async fn get_guardian_public_keys_blocking( &self, ) -> BTreeMap<PeerId, PublicKey>

Blocks till the client has synced the guardian public key set (introduced in version 0.4) and returns it. Once it has been fetched once this function is guaranteed to return immediately.

pub fn handle_global_rpc( &self, method: String, params: Value, ) -> BoxStream<'_, Result<Value>>

pub async fn log_event<E>(&self, module_id: Option<ModuleInstanceId>, event: E)

where E: Event + Send,

pub async fn log_event_dbtx<E, Cap>( &self, dbtx: &mut DatabaseTransaction<'_, Cap>, module_id: Option<ModuleInstanceId>, event: E, )

where E: Event + Send, Cap: Send,

pub async fn log_event_raw_dbtx<Cap>( &self, dbtx: &mut DatabaseTransaction<'_, Cap>, kind: EventKind, module: Option<(ModuleKind, ModuleInstanceId)>, payload: Vec<u8>, transient: bool, )

where Cap: Send,

pub async fn handle_events<F, R, K>( &self, pos_key: &K, call_fn: F, ) -> Result<()>

where K: DatabaseKey + DatabaseRecord + MaybeSend + MaybeSync + DatabaseRecord<Value = EventLogId>, F: Fn(&mut DatabaseTransaction<'_, NonCommittable>, EventLogEntry) -> R, R: Future<Output = Result<()>>,

pub async fn get_event_log( &self, pos: Option<EventLogId>, limit: u64, ) -> Vec<(EventLogId, EventKind, Option<(ModuleKind, ModuleInstanceId)>, u64, Value)>

pub async fn get_event_log_dbtx<Cap>( &self, dbtx: &mut DatabaseTransaction<'_, Cap>, pos: Option<EventLogId>, limit: u64, ) -> Vec<(EventLogId, EventKind, Option<(ModuleKind, ModuleInstanceId)>, u64, Value)>

where Cap: Send,

Register to receiver all new transient (unpersisted) events
