A module for representing and extracting typed transactional rollup parameters.

type deposit_parameters = {

ex_ticket : Ticket_scanner.ex_ticket;
l2_destination : Script_typed_ir.tx_rollup_l2_address;

}

A type representing deposit parameters for transactional rollups. Deposit parameters consist of a ticket of arbitrary content along with a layer-2 destination address.

val get_deposit_parameters : 
  ('a, 'comparable) Script_typed_ir.ty ->
  'a ->
  deposit_parameters

get_deposit_parameters ty value returns ex_ticket and a tx_rollup_l2_address from a michelson typed value. if ty is not of a pair of ticket and tx_rollup_l2_address then it fails with Tx_rollup_errors.Wrong_deposit_parameters.

This function is intended to be used to enforce the type of the transaction to a tx_rollup%deposit. It must be used both in ticket_diffs_of_operations to account for the ticket deposited and in apply to retrieve the ticket when applying the transaction to a tx_rollup.
