val compare_balance : balance -> balance -> int

Compares two balances.

type balance_update =

| Debited of Tez_repr.t
| Credited of Tez_repr.t

A credit or debit of tez to a balance.

type update_origin =

| Block_application

Update from a block application

(*
Update from a protocol migration
*)
| Subsidy
(*
Update from an inflationary subsidy

An origin of a balance update

val compare_update_origin : update_origin -> update_origin -> int

Compares two origins.

type balance_updates = (balance * balance_update * update_origin) list

A list of balance updates. Duplicates may happen. For example, an entry of the form (Rewards (b,c), Credited am, ...) indicates that the balance of frozen rewards has been increased by am for baker b and cycle c.

val balance_updates_encoding : 
  balance_updates Tezos_protocol_environment_014_PtKathma.Data_encoding.t

The property Json.destruct (Json.construct balance_updates) = balance_updates does not always hold for balance_updates_encoding when balance_updates contains entries of the form (_, _ Tez_repr.zero, _). This is because the balance_update (_ Tez_repr.zero) always decodes into (Credited Tez_repr.zero).

val group_balance_updates : 
  balance_updates ->
  balance_updates Tezos_protocol_environment_014_PtKathma.Error_monad.tzresult

Group updates by (balance x origin), and remove zero-valued balances.
