Trait Implementations

impl Default for MockInvokeContext

fn default() -> Self

Returns the “default value” for a type.

impl InvokeContext for MockInvokeContext

fn push(&mut self, _key: &Pubkey) -> Result<(), InstructionError>

Push a program ID on to the invocation stack

fn pop(&mut self)

Pop a program ID off of the invocation stack

fn invoke_depth(&self) -> usize

Current depth of the invocation stake

fn verify_and_update(
    &mut self,
    _message: &Message,
    _instruction: &CompiledInstruction,
    _accounts: &[Rc<RefCell<AccountSharedData>>],
    _caller_pivileges: Option<&[bool]>
) -> Result<(), InstructionError>

Verify and update PreAccount state based on program execution

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