Implementations

impl MessageProcessor

pub fn add_program(
    &mut self,
    program_id: Pubkey,
    process_instruction: ProcessInstruction
)

Add a static entrypoint to intercept instructions before the dynamic loader.

pub fn add_loader(
    &mut self,
    program_id: Pubkey,
    process_instruction: ProcessInstructionWithContext
)

pub fn set_cross_program_support(&mut self, is_supported: bool)

pub fn set_compute_budget(&mut self, compute_budget: ComputeBudget)

pub fn process_cross_program_instruction(
    &self,
    message: &Message,
    executable_accounts: &[(Pubkey, RefCell<Account>)],
    accounts: &[Rc<RefCell<Account>>],
    invoke_context: &mut dyn InvokeContext
) -> Result<(), InstructionError>

Process a cross-program instruction This method calls the instruction's program entrypoint function

pub fn create_pre_accounts(
    message: &Message,
    instruction: &CompiledInstruction,
    accounts: &[Rc<RefCell<Account>>]
) -> Vec<PreAccount>

Record the initial state of the accounts so that they can be compared after the instruction is processed

pub fn verify_account_references(
    accounts: &[(Pubkey, RefCell<Account>)]
) -> Result<(), InstructionError>

Verify there are no outstanding borrows

pub fn verify(
    message: &Message,
    instruction: &CompiledInstruction,
    pre_accounts: &[PreAccount],
    executable_accounts: &[(Pubkey, RefCell<Account>)],
    accounts: &[Rc<RefCell<Account>>],
    rent: &Rent
) -> Result<(), InstructionError>

Verify the results of an instruction

pub fn process_message(
    &self,
    message: &Message,
    loaders: &[Vec<(Pubkey, RefCell<Account>)>],
    accounts: &[Rc<RefCell<Account>>],
    rent_collector: &RentCollector,
    log_collector: Option<Rc<LogCollector>>
) -> Result<(), TransactionError>

Process a message. This method calls each instruction in the message over the set of loaded Accounts The accounts are committed back to the bank only if every instruction succeeds

pub fn builtin_program_ids(&self) -> Vec<Pubkey>
