Struct FungibleBalanceArgs 

pub struct FungibleBalanceArgs<'a> {
    pub address_ptr: NonNull<<Address as IoType>::PointerType>,
    pub address_size: u32,
    pub address_capacity: u32,
    pub ok_result_ptr: NonNull<Balance>,
    /* private fields */
}

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

address_ptr: NonNull<<Address as IoType>::PointerType>

address_size: u32

Size of the contents address_ptr points to

address_capacity: u32

Capacity of the contents address_ptr points to

ok_result_ptr: NonNull<Balance>

Implementations

impl<'a> FungibleBalanceArgs<'a>

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

Create a new instance.

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