Struct StateIsEmptyArgs 

pub struct StateIsEmptyArgs<'a> {
    pub contract_state_ptr: NonNull<Address>,
    pub ok_result_ptr: NonNull<Bool>,
    /* private fields */
}

Data structure containing expected input for external method invocation, eventually calling state_is_empty() on the other side by the host.

This can be used with Env, though there are helper methods on this provided by extension trait that allow not dealing with this struct directly in simpler cases.

Fields

contract_state_ptr: NonNull<Address>

ok_result_ptr: NonNull<Bool>

Implementations

impl<'a> StateIsEmptyArgs<'a>

pub fn new( contract_state: &'a Address, ok_result: &'a mut MaybeUninit<Bool>, ) -> Self

Create a new instance.

NOTE: Make sure to query updated sizes of arguments after calling the contract.
