Struct FungibleBalanceArgs

#[repr(C)]
pub struct FungibleBalanceArgs {
    pub address_ptr: NonNull<<Address as IoType>::PointerType>,
    pub address_size: NonNull<u32>,
    pub ok_result_ptr: NonNull<Balance>,
    pub ok_result_size: *mut u32,
    pub ok_result_capacity: NonNull<u32>,
}

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: NonNull<u32>

Size of the contents address_ptr points to

ok_result_ptr: NonNull<Balance>

ok_result_size: *mut u32

Size of the contents ok_result_ptr points to

ok_result_capacity: NonNull<u32>

Capacity of the allocated memory ok_result_ptr points to
