Trait Implementations

impl AsyncClient for ThinClient

fn async_send_transaction(
    &self,
    transaction: Transaction

    message: Message,
    recent_blockhash: Hash
) -> TransportResult<Signature>

fn async_send_instruction(
    &self,
    keypair: &Keypair,
    instruction: Instruction,
    recent_blockhash: Hash
) -> TransportResult<Signature>
