Thanks to the pattern synonyms, you can treat this as a sum type with
constructors QueryResultSuccess and QueryResultEraMismatch.
The Either type represents values with two possibilities: a value of
type Either a bLeft aRight b
The Either type is sometimes used to represent a value which is
either correct or an error; by convention, the Left constructor is
used to hold an error value and the Right constructor is used to
hold a correct value (mnemonic: "right" also means "correct").
Examples
The type Either String IntString or an Int. The Left constructor can be used only on
Strings, and the Right constructor can be used only on Ints:
>>>let s = Left "foo" :: Either String Int>>>sLeft "foo">>>let n = Right 3 :: Either String Int>>>nRight 3>>>:type ss :: Either String Int>>>:type nn :: Either String Int
The fmap from our Functor instance will ignore Left values, but
will apply the supplied function to values contained in a Right:
>>>let s = Left "foo" :: Either String Int>>>let n = Right 3 :: Either String Int>>>fmap (*2) sLeft "foo">>>fmap (*2) nRight 6
The Monad instance for Either allows us to chain together multiple
actions which may fail, and fail overall if any of the individual
steps failed. First we'll write a function that can either parse an
Int from a Char, or fail.
>>>import Data.Char ( digitToInt, isDigit )>>>:{let parseEither :: Char -> Either String Int parseEither c | isDigit c = Right (digitToInt c) | otherwise = Left "parse error">>>:}
The following should work, since both '1' and '2' can be
parsed as Ints.
>>>:{let parseMultiple :: Either String Int parseMultiple = do x <- parseEither '1' y <- parseEither '2' return (x + y)>>>:}
>>>parseMultipleRight 3
But the following should fail overall, since the first operation where
we attempt to parse 'm' as an Int will fail:
>>>:{let parseMultiple :: Either String Int parseMultiple = do x <- parseEither 'm' y <- parseEither '2' return (x + y)>>>:}
>>>parseMultipleLeft "parse error"

NOTE: the CardanoLedgerState contains more than just the current era's
LedgerState. We don't give access to those internal details through the
pattern synonyms. This is also the reason the pattern synonyms are not
bidirectional.
data family LedgerState blk Source #
Ledger state associated with a block
This is the Consensus notion of a ledger state. Each block type is
associated with one of the Ledger types for the ledger state. Virtually
every concept in this codebase revolves around this type, or the referenced
blk. Whenever we use the type variable l, we intend to denote that the
expected instantiation is either a LedgerState or some wrapper over it
(like the ExtLedgerState).
The main operations we can do with a LedgerState are ticking (defined in
IsLedger), and applying a block (defined in
ApplyBlock).

NOTE: the CardanoChainDepState contains more than just the current era's

pattern synonyms. This is also the reason the pattern synonyms are not
bidirectional.
data HardForkState (f ∷ Type → Type) (xs ∷ [Type]) where Source #
Generic hard fork state
This is used both for the consensus state and the ledger state.
By using a telescope with f ~ LedgerState, we will keep track of Past
information for eras before the current one:
TZ currentByronState TZ pastByronState $ TZ currentShelleyState TZ pastByronState $ TS pastShelleyState $ TZ currentAllegraState ...
These are some intuitions on how the Telescope operations behave for this type:
extend
Suppose we have a telescope containing the ledger state. The "how to extend" argument would take, say, the final Byron state to the initial Shelley state; and "where to extend from" argument would indicate when we want to extend: when the current slot number has gone past the end of the Byron era.
retract
Suppose we have a telescope containing the consensus state. When we rewind
the consensus state, we might cross a hard fork transition point. So we first
retract the telescope to the era containing the slot number that we want
to rewind to, and only then call rewindChainDepState on that era. Of course,
retraction may fail (we might not have past consensus state to rewind to
anymore); this failure would require a choice for a particular monad m.
align
Suppose we have one telescope containing the already-ticked ledger state, and
another telescope containing the consensus state. Since the ledger state has
already been ticked, it might have been advanced to the next era. If this
happens, we should then align the consensus state with the ledger state,
moving it also to the next era, before we can do the consensus header
validation check. Note that in this particular example, the ledger state will
always be ahead of the consensus state, never behind; alignExtend can be
used in this case.
