Required methods

fn send_message(
    &self,
    keypairs: &[&Keypair],
    message: Message
) -> Result<Signature>

Create a transaction from the given message, and send it to the server, retrying as-needed.

fn send_instruction(
    &self,
    keypair: &Keypair,
    instruction: Instruction
) -> Result<Signature>

Create a transaction from a single instruction that only requires a single signer. Then send it to the server, retrying as-needed.

fn transfer(
    &self,
    lamports: u64,
    keypair: &Keypair,
    pubkey: &Pubkey
) -> Result<Signature>

Transfer lamports from keypair to pubkey, retrying until the transfer completes or produces and error.

fn get_account_data(&self, pubkey: &Pubkey) -> Result<Option<Vec<u8>>>

Get an account or None if not found.

fn get_account(&self, pubkey: &Pubkey) -> Result<Option<Account>>

Get an account or None if not found.

fn get_balance(&self, pubkey: &Pubkey) -> Result<u64>

Get account balance or 0 if not found.

fn get_recent_blockhash(&self) -> Result<(Hash, FeeCalculator)>

Get recent blockhash

fn get_signature_status(
    &self,
    signature: &Signature
) -> Result<Option<Result<()>>>

Get signature status.

fn get_slot(&self) -> Result<u64>

Get last known slot

fn get_transaction_count(&self) -> Result<u64>

Get transaction count

fn poll_for_signature_confirmation(
    &self,
    signature: &Signature,
    min_confirmed_blocks: usize
) -> Result<()>

Poll until the signature has been confirmed by at least min_confirmed_blocks

fn poll_for_signature(&self, signature: &Signature) -> Result<()>

Poll to confirm a transaction.

fn get_new_blockhash(&self, blockhash: &Hash) -> Result<(Hash, FeeCalculator)>
