Expand description

This defines a generic trait used to interact with the Diem blockchain. In production, this will be talking to a JSON-RPC service. For tests, this may be an executor and storage directly.

Required Methods§

source

fn diem_timestamp(&self) -> Result<u64, Error>

Retrieves the current time from the blockchain, this is returned as microseconds.

source

fn last_reconfiguration(&self) -> Result<u64, Error>

Retrieves the last reconfiguration time from the blockchain, this is returned as microseconds.

source

fn retrieve_sequence_number(&self, account: AccountAddress) -> Result<u64, Error>

Retrieve current sequence number for the provided account.

source

fn submit_transaction(&self, transaction: Transaction) -> Result<(), Error>

Submits a transaction to the block chain and returns successfully if the transaction was successfully submitted. It does not necessarily mean the transaction successfully executed.

source

fn retrieve_validator_config( &self, account: AccountAddress ) -> Result<ValidatorConfig, Error>

Retrieves the ValidatorConfig at the specified AccountAddress if one exists.

source

fn retrieve_validator_info( &self, account: AccountAddress ) -> Result<ValidatorInfo, Error>

Retrieves the ValidatorInfo for the specified account from the current ValidatorSet if one exists.

source

fn retrieve_account_state( &self, account: AccountAddress ) -> Result<AccountState, Error>

Fetches the AccountState associated with a specific account. This is currently only used by test code, but it’s not completely inconceivable that non-test code will want access to this in the future.
