Required Methods§

source

fn send_and_confirm_message<T: Signers>( &self, keypairs: &T, message: Message ) -> Result<Signature>

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

source

fn send_and_confirm_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.

source

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

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

source

Get an account or None if not found.

source

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

Get an account or None if not found.

source

fn get_account_with_commitment( &self, pubkey: &Pubkey, commitment_config: CommitmentConfig ) -> Result<Option<Account>>

source

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

Get account balance or 0 if not found.

source

fn get_balance_with_commitment( &self, pubkey: &Pubkey, commitment_config: CommitmentConfig ) -> Result<u64>

source

fn get_recent_blockhash_with_commitment( &self, commitment_config: CommitmentConfig ) -> Result<(Hash, FeeCalculator, Slot)>

👎Deprecated since 1.9.0: Please use get_latest_blockhash_with_commitment and get_latest_blockhash_with_commitment instead
