Transaction

Change-transaction

Modifying constructor for transaction structures.

Syntax

(change-transaction x 
                    [:nonce <nonce>] 
                    [:gas-price <gas-price>] 
                    [:gas-limit <gas-limit>] 
                    [:to <to>] 
                    [:value <value>] 
                    [:init/data <init/data>] 
                    [:sign-v <sign-v>] 
                    [:sign-r <sign-r>] 
                    [:sign-s <sign-s>])

This is an often useful alternative to make-transaction.

We construct a new transaction structure that is a copy of x, except that you can explicitly change some particular fields. Any fields you don't mention just keep their values from x.

Definition

This is an ordinary change- macro introduced by fty::defprod.

Macro: change-transaction

(defmacro change-transaction (x &rest args)
  (std::change-aggregate 'transaction
                         x args
                         '((:nonce . transaction->nonce)
                           (:gas-price . transaction->gas-price)
                           (:gas-limit . transaction->gas-limit)
                           (:to . transaction->to)
                           (:value . transaction->value)

                           (:sign-s . transaction->sign-s))
                         'change-transaction
                         'nil))
