Implementations

impl MessageProcessor

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

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 create_message(
    instruction: &Instruction,
    keyed_accounts: &[&KeyedAccount<'_>],
    signers: &[Pubkey],
    invoke_context: &Ref<'_, &mut dyn InvokeContext>
) -> Result<(Message, Pubkey, usize), InstructionError>

pub fn native_invoke(
    invoke_context: &mut dyn InvokeContext,
    instruction: Instruction,
    keyed_account_indices: &[usize],
    signers: &[Pubkey]
) -> Result<(), InstructionError>

Entrypoint for a cross-program invocation from a native program

pub fn process_cross_program_instruction(
    message: &Message,
    executable_accounts: &[(Pubkey, Rc<RefCell<AccountSharedData>>)],
    accounts: &[(Pubkey, Rc<RefCell<AccountSharedData>>)],
    caller_write_privileges: &[bool],
    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: &[(Pubkey, Rc<RefCell<AccountSharedData>>)]
) -> 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, Rc<RefCell<AccountSharedData>>)]
) -> Result<(), InstructionError>

Verify there are no outstanding borrows

pub fn verify(
    message: &Message,
    instruction: &CompiledInstruction,
    pre_accounts: &[PreAccount],
    executable_accounts: &[(Pubkey, Rc<RefCell<AccountSharedData>>)],
    accounts: &[(Pubkey, Rc<RefCell<AccountSharedData>>)],
    rent: &Rent,
    timings: &mut ExecuteDetailsTimings,
    logger: Rc<RefCell<dyn Logger>>,
    updated_verify_policy: bool,
    demote_program_write_locks: bool
) -> Result<(), InstructionError>

Verify the results of an instruction

pub fn process_message(
    &self,
    message: &Message,
    loaders: &[Vec<(Pubkey, Rc<RefCell<AccountSharedData>>)>],
    accounts: &[(Pubkey, Rc<RefCell<AccountSharedData>>)],
    rent_collector: &RentCollector,
    log_collector: Option<Rc<LogCollector>>,
    executors: Rc<RefCell<Executors>>,
    instruction_recorders: Option<&[InstructionRecorder]>,
    feature_set: Arc<FeatureSet>,
    bpf_compute_budget: BpfComputeBudget,
    compute_meter: Rc<RefCell<dyn ComputeMeter>>,
    timings: &mut ExecuteDetailsTimings,
    account_db: Arc<Accounts>,
    ancestors: &Ancestors,
    voter_grp: &dyn VoteModerator
) -> 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
