Struct TxHandlerAuthorizeArgs

#[repr(C)]
pub struct TxHandlerAuthorizeArgs {
    pub header_ptr: NonNull<<TransactionHeader as IoType>::PointerType>,
    pub header_size: NonNull<u32>,
    pub read_slots_ptr: NonNull<<TxHandlerSlots as IoType>::PointerType>,
    pub read_slots_size: NonNull<u32>,
    pub write_slots_ptr: NonNull<<TxHandlerSlots as IoType>::PointerType>,
    pub write_slots_size: NonNull<u32>,
    pub payload_ptr: NonNull<<TxHandlerPayload as IoType>::PointerType>,
    pub payload_size: NonNull<u32>,
    pub seal_ptr: NonNull<<TxHandlerSeal as IoType>::PointerType>,
    pub seal_size: NonNull<u32>,
}

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