Struct PlaygroundBalance2Args

#[repr(C)]
pub struct PlaygroundBalance2Args {
    pub target_ptr: NonNull<Address>,
    pub balance_ptr: NonNull<<MaybeData<Balance> as IoType>::PointerType>,
    pub balance_size: *mut u32,
    pub balance_capacity: NonNull<u32>,
}

Data structure containing expected input for external method invocation, eventually calling playground_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

Size of the contents balance_ptr points to

balance_capacity: NonNull<u32>

Capacity of the allocated memory balance_ptr points to
