A chain query client responsible for all read actions from the blockchain (no write)

Required Methods

fn get_network(&self) -> Network

Query the network id (not identical to network magic)

fn query_system_start( &self, ) -> impl Future<Output = Result<DateTime<Utc>, ChainQueryError>>

fn query_era_summaries( &self, ) -> impl Future<Output = Result<Vec<EraSummary>, ChainQueryError>>

fn query_protocol_params( &self, ) -> impl Future<Output = Result<ProtocolParameters, ChainQueryError>>

Query protocol parameters

fn query_tip(&self) -> impl Future<Output = Result<ChainTip, ChainQueryError>>

fn query_utxos_by_addr( &self, address: &Address, ) -> impl Future<Output = Result<BTreeMap<TransactionInput, FullTransactionOutput>, ChainQueryError>>

Query UTxOs at an address

fn query_utxos_by_ref( &self, references: Vec<&TransactionInput>, ) -> impl Future<Output = Result<BTreeMap<TransactionInput, FullTransactionOutput>, ChainQueryError>>

Dyn Compatibility

This trait is not dyn compatible.

In older versions of Rust, dyn compatibility was called "object safety", so this trait is not object safe.
