Function assert_current_call_valid_authwit

pub fn assert_current_call_valid_authwit<let N: u32>(
    context: &mut PrivateContext,
    on_behalf_of: AztecAddress,
)

Assert that on_behalf_of has authorized the current call with a valid authentication witness

Compute the inner_hash using the msg_sender, selector and args_hash and then make a call out to the on_behalf_of contract to verify that the inner_hash is valid.

Additionally, this function emits the identifying information of the call as an offchain effect so PXE can rely the information to the user/wallet in a readable way. To that effect, it is generic over N, where N is the number of arguments the authorized functions takes. This is used to load the arguments from the execution cache. This function is intended to be called via a macro, which will use the turbofish operator to specify the number of arguments.

@param on_behalf_of The address that has allegedly authorized the current call
