Struct ExampleBalance2Args

Source
#[repr(C)]
pub struct ExampleBalance2Args { pub target_ptr: NonNull<Address>, pub balance_ptr: NonNull<<MaybeData<Balance> as IoType>::PointerType>, pub balance_size: *mut u32, pub balance_capacity: NonNull<u32>, pub ok_result_ptr: NonNull<()>, pub ok_result_size: *mut u32, pub ok_result_capacity: NonNull<u32>, }
Expand description

Data structure containing expected input for external method invocation, eventually calling balance2() 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: *mut u32

§balance_capacity: NonNull<u32>

Capacity of the allocated memory balance_ptr points to

§ok_result_ptr: NonNull<()>§ok_result_size: *mut u32

Size of the contents ok_result_ptr points to

§ok_result_capacity: NonNull<u32>
