Struct StateWriteArgs

#[repr(C)]
pub struct StateWriteArgs {
    pub contract_state_ptr: NonNull<Address>,
    pub new_state_ptr: NonNull<<VariableBytes<MAX_STATE_SIZE> as IoType>::PointerType>,
    pub new_state_size: NonNull<u32>,
    pub ok_result_ptr: NonNull<()>,
    pub ok_result_size: *mut u32,
    pub ok_result_capacity: NonNull<u32>,
}

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