Implementations

impl EthereumClient<HttpProvider>

pub fn new(url: String) -> Result<Self, EthereumServiceError>

Connects to an existing Ethereum node and creates an EthereumClient if successful.

Trait Implementations

impl<M: Clone> Clone for EthereumClient<M>

fn clone(&self) -> EthereumClient<M>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl EthereumQueries for EthereumClient<HttpProvider>

type Error = EthereumServiceError

fn get_accounts<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<Vec<String>, EthereumServiceError>> + Send + 'async_trait>>

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

Lists all the accounts of the Ethereum node.

fn get_block_number<'life0, 'async_trait>( &'life0 self, ) -> Pin<Box<dyn Future<Output = Result<u64, EthereumServiceError>> + Send + 'async_trait>>

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

Gets the latest block number of the Ethereum node.

fn get_balance<'life0, 'life1, 'async_trait>( &'life0 self, address: &'life1 str, block_number: u64, ) -> Pin<Box<dyn Future<Output = Result<U256, EthereumServiceError>> + Send + 'async_trait>>

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

Gets the balance of the specified address at the specified block number. if no block number is specified then the balance of the latest block is returned.

fn read_events<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, contract_address: &'life1 str, event_name_expanded: &'life2 str, from_block: u64, to_block: u64, ) -> Pin<Box<dyn Future<Output = Result<Vec<EthereumEvent>, EthereumServiceError>> + Send + 'async_trait>>

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

Reads the events of the smart contract.

fn non_executive_call<'life0, 'life1, 'life2, 'async_trait>( &'life0 self, contract_address: &'life1 str, data: Bytes, from: &'life2 str, block: u64, ) -> Pin<Box<dyn Future<Output = Result<Bytes, EthereumServiceError>> + Send + 'async_trait>>

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

The operation done with eth_call on Ethereum returns a result but are not committed to the blockchain. This can be useful for example for executing function that are const and allow to inspect the contract without modifying it.
