Struct PlaygroundBalanceOutputArgs 

pub struct PlaygroundBalanceOutputArgs<'a> {
    pub target_ptr: NonNull<Address>,
    pub balance_ptr: NonNull<<MaybeData<Balance> as IoType>::PointerType>,
    pub balance_size: u32,
    pub balance_capacity: u32,
    pub balance_2_ptr: NonNull<<Balance as IoType>::PointerType>,
    pub balance_2_size: u32,
    pub balance_2_capacity: u32,
    /* private fields */
}

Data structure containing expected input for external method invocation, eventually calling playground_balance_output() 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

target_ptr: NonNull<Address>

balance_ptr: NonNull<<MaybeData<Balance> as IoType>::PointerType>

balance_size: u32

Size of the contents balance_ptr points to

balance_capacity: u32

Capacity of the allocated memory balance_ptr points to

balance_2_ptr: NonNull<<Balance as IoType>::PointerType>

balance_2_size: u32

Size of the contents balance_2_ptr points to

balance_2_capacity: u32

Capacity of the allocated memory balance_2_ptr points to

Implementations

impl<'a> PlaygroundBalanceOutputArgs<'a>

pub fn new( target: &'a Address, balance: &'a mut MaybeData<Balance>, balance_2: &'a mut Balance, ) -> Self

Create a new instance.

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