pub fn push(
    &mut self,
    message: &Message,
    instruction: &CompiledInstruction,
    program_indices: &[usize],

) -> Result<(), InstructionError>

Push a stack frame onto the invocation stack

pub fn pop(&mut self)

Pop a stack frame from the invocation stack

pub fn invoke_depth(&self) -> usize

Current depth of the invocation stack

pub fn native_invoke(
    &mut self,
    instruction: Instruction,
    signers: &[Pubkey]
) -> Result<(), InstructionError>

pub fn create_message(
    &mut self,
    instruction: &Instruction,
    signers: &[Pubkey]
) -> Result<(Message, Vec<bool, Global>, Vec<usize, Global>), InstructionError>

    &mut self,
    message: &Message,
    instruction: &CompiledInstruction,
    program_indices: &[usize],
    account_indices: &[usize],
    caller_write_privileges: &[bool]
) -> ProcessInstructionResult

pub fn get_caller(&self) -> Result<&Pubkey, InstructionError>

Get the program ID of the currently executing program

pub fn get_loader(&self) -> Result<Pubkey, InstructionError>

Get the owner of the currently executing program

pub fn remove_first_keyed_account(&mut self) -> Result<(), InstructionError>

👎 Deprecated since 1.9.0:

To be removed together with remove_native_loader

Removes the first keyed account

pub fn get_keyed_accounts(
    &self
) -> Result<&[KeyedAccount<'_>], InstructionError>

Get the list of keyed accounts

pub fn get_instruction_keyed_accounts(
    &self
