Description

This module defines core type families which we know to vary from era to era.

Families in this module should be indexed on era.

It is intended for qualified import: > import qualified Cardano.Ledger.Core as Core

upgradeTxEraTx (PreviousEra era) ⇒ Tx (PreviousEra era) → Either (TxUpgradeError era) (Tx era) Source #

txIdTxEraTx era ⇒ Tx era → TxId (EraCrypto era) Source #

class (Val (Value era), ToJSON (TxOut era), DecCBOR (Value era), DecCBOR (CompactForm (Value era)), EncCBOR (Value era), ToCBOR (TxOut era), EncCBOR (TxOut era), DecCBOR (TxOut era), DecShareCBOR (TxOut era), Share (TxOut era) ~ Interns (Credential 'Staking (EraCrypto era)), NoThunks (TxOut era), NFData (TxOut era), Show (TxOut era), Eq (TxOut era), EraPParams era) ⇒ EraTxOut era where Source #

Abstract interface into specific fields of a TxOut

Associated Types

type TxOut era = (r ∷ Type) | r → era Source #

The output of a UTxO for a particular era

Methods

mkBasicTxOutHasCallStackAddr (EraCrypto era) → Value era → TxOut era Source #

upgradeTxOutEraTxOut (PreviousEra era) ⇒ TxOut (PreviousEra era) → TxOut era Source #

Every era, except Shelley, must be able to upgrade a TxOut from a previous era.

valueTxOutLLens' (TxOut era) (Value era) Source #

compactValueTxOutLHasCallStackLens' (TxOut era) (CompactForm (Value era)) Source #

valueEitherTxOutLLens' (TxOut era) (Either (Value era) (CompactForm (Value era))) Source #

Lens for getting and setting in TxOut either an address or its compact version by doing the least amount of work.

addrTxOutLLens' (TxOut era) (Addr (EraCrypto era)) Source #

compactAddrTxOutLLens' (TxOut era) (CompactAddr (EraCrypto era)) Source #

addrEitherTxOutLLens' (TxOut era) (Either (Addr (EraCrypto era)) (CompactAddr (EraCrypto era))) Source #

Lens for getting and setting in TxOut either an address or its compact version by doing the least amount of work.

The utility of this function comes from the fact that TxOut usually stores the address in either one of two forms: compacted or unpacked. In order to avoid extroneous conversions in getTxOutAddr and getTxOutCompactAddr we can define just this functionality. Also sometimes it is crucial to know at the callsite which form of address we have readily available without any conversions (eg. searching millions of TxOuts for a particular address)

getMinCoinSizedTxOutPParams era → Sized (TxOut era) → Coin Source #

Produce the minimum lovelace that a given transaction output must contain. Information about the size of the TxOut is required in some eras. Use getMinCoinTxOut if you don't have the size readily available to you.

getMinCoinTxOutPParams era → TxOut era → Coin Source #

Same as getMinCoinSizedTxOut, except information about the size of TxOut will be computed by serializing the TxOut. If the size turns out to be not needed, then serialization will have no overhead, since it is computed lazily.

isAdaOnlyTxOutFEraTxOut era ⇒ SimpleGetter (TxOut era) Bool Source #

This is a getter that implements an efficient way to check whether TxOut contains ADA only.

class (EraTxOut era, EraTxCert era, EraPParams era, HashAnnotated (TxBody era) EraIndependentTxBody (EraCrypto era), DecCBOR (Annotator (TxBody era)), EncCBOR (TxBody era), ToCBOR (TxBody era), NoThunks (TxBody era), NFData (TxBody era), Show (TxBody era), Eq (TxBody era), EqRaw (TxBody era)) ⇒ EraTxBody era where Source #

Associated Types

type TxBody era = (r ∷ Type) | r → era Source #

The body of a transaction.

type TxBodyUpgradeError era ∷ Type Source #

Methods

mkBasicTxBodyTxBody era Source #

auxDataHashTxBodyLLens' (TxBody era) (StrictMaybe (AuxiliaryDataHash (EraCrypto era))) Source #

spendableInputsTxBodyFSimpleGetter (TxBody era) (Set (TxIn (EraCrypto era))) Source #

This getter will produce all inputs from the UTxO map that this transaction might spend, which ones will depend on the validity of the transaction itself. Starting in Alonzo this will include collateral inputs.

allInputsTxBodyFSimpleGetter (TxBody era) (Set (TxIn (EraCrypto era))) Source #

This getter will produce all inputs from the UTxO map that this transaction is referencing, even if some of them cannot be spent by the transaction. For example starting with Babbage era it will also include reference inputs.

certsTxBodyLLens' (TxBody era) (StrictSeq (TxCert era)) Source #

getTotalDepositsTxBody Source #

Arguments

PParams era 
→ (KeyHash 'StakePool (EraCrypto era) → Bool)

Check whether stake pool is registered or not

TxBody era 
Coin 

Compute the total deposits from the certificates in a TxBody.

This is the contribution of a TxBody towards the consumed amount by the transaction

getTotalRefundsTxBody Source #

Arguments

PParams era 
→ (Credential 'Staking (EraCrypto era) → Maybe Coin)

Lookup current deposit for Staking credential if one is registered

→ (Credential 'DRepRole (EraCrypto era) → Maybe Coin)

Lookup current deposit for DRep credential if one is registered

TxBody era 
Coin 

Compute the total refunds from the Certs of a TxBody.

This is the contribution of a TxBody towards produced amount by the transaction

getGenesisKeyHashCountTxBodyTxBody era → Int Source #

This function is not used in the ledger rules. It is only used by the downstream tooling to figure out how many witnesses should be supplied for Genesis keys.

upgradeTxBodyEraTxBody (PreviousEra era) ⇒ TxBody (PreviousEra era) → Either (TxBodyUpgradeError era) (TxBody era) Source #

Upgrade the transaction body from the previous era.

This can fail where elements of the transaction body are deprecated. Compare this to translateEraThroughCBOR: - upgradeTxBody will use the Haskell representation, but will not preserve the serialised form. However, it will be suitable for iterated translation through eras. - translateEraThroughCBOR will preserve the binary representation, but is not guaranteed to work through multiple eras - that is, the serialised representation from era n is guaranteed valid in era n + 1, but not necessarily in era n + 2.

txIdTxBodyEraTxBody era ⇒ TxBody era → TxId (EraCrypto era) Source #

class (Era era, Eq (TxAuxData era), EqRaw (TxAuxData era), Show (TxAuxData era), NoThunks (TxAuxData era), ToCBOR (TxAuxData era), EncCBOR (TxAuxData era), DecCBOR (Annotator (TxAuxData era)), HashAnnotated (TxAuxData era) EraIndependentTxAuxData (EraCrypto era)) ⇒ EraTxAuxData era where Source #

metadataTxAuxDataLLens' (TxAuxData era) (Map Word64 Metadatum) Source #

upgradeTxAuxDataEraTxAuxData (PreviousEra era) ⇒ TxAuxData (PreviousEra era) → TxAuxData era Source #

Every era, except Shelley, must be able to upgrade a TxAuxData from a previous era.

Warning - Important to note that any memoized binary representation will not be preserved. If you need to retain underlying bytes you can use translateEraThroughCBOR

hashTxAuxDataTxAuxData era → AuxiliaryDataHash (EraCrypto era) Source #

Typeclass for script data types. Allows for script validation and hashing. You must understand the role of SafeToHash and scriptPrefixTag to make new instances. scriptPrefixTag is a magic number representing the tag of the script language. For each new script language defined, a new tag is chosen and the tag is included in the script hash for a script. The safeToHash constraint ensures that Scripts are never reserialised.

type NativeScript era = (r ∷ Type) | r → era Source #

Methods

Restrict an era to the specific era through the protocol version. This is equivalent to (inEra (Crypto era) ~ era)

type family ProtVerAtMost era (h ∷ Nat) ∷ Constraint where ... Source #

Restrict a lower and upper bounds of the protocol version for the particular era

atLeastEraAtLeastEra eraName era ⇒ () Source #

Enforce era to be at least the specified era at the type level. In other words compiler will produce type error when applied to eras prior to the specified era. This function should be used in order to avoid redundant constraints warning.

For example these will type check

>>> atLeastEra @BabbageEra @(ConwayEra StandardCrypto)
>>> atLeastEra @BabbageEra @(BabbageEra StandardCrypto)

However this will result in a type error

>>> atLeastEra @BabbageEra @(AlonzoEra StandardCrypto)

atMostEraAtMostEra eraName era ⇒ () Source #

Enforce era to be at most the specified era at the type level. In other words compiler will produce type error when applied to eras prior to the specified era. This function should be used in order to avoid redundant constraints warning.

For example these will type check

>>> atMostEra @BabbageEra @(ShelleyEra StandardCrypto)
>>> atMostEra @AlonzoEra @(MaryEra StandardCrypto)

However this will result in a type error

>>> atMostEra @BabbageEra @(ConwayEra StandardCrypto)

eraProtVerLow ∷ ∀ era. Era era ⇒ Version Source #

fromEraCBOR ∷ ∀ era t s. (Era era, DecCBOR t) ⇒ Decoder s t Source #

Convert a type that implements DecCBOR to plain Decoder using the lowest protocol version for the supplied era

This action should not be used for decoders that require access to original bytes, use toPlainDecoder instead.

fromEraShareCBOR ∷ ∀ era t s. (Era era, DecShareCBOR t) ⇒ Decoder s t Source #

Convert a type that implements DecShareCBOR to plain Decoder using the lowest protocol version for the supplied era

This action should not be used for decoders that require access to original bytes, use toPlainDecoder instead.

eraDecoder ∷ ∀ era t s. Era era ⇒ Decoder s t → Decoder s t Source #

Convert a versioned Decoder to plain a Decoder using the lowest protocol version for the supplied era

This action should not be used for decoders that require access to original bytes, use toPlainDecoder instead.

  • Segregated Witness

The idea of segregated witnessing is to alter the encoding of transactions in a block such that the witnesses (the information needed to verify the validity of the transactions) can be stored separately from the body (the information needed to update the ledger state). In this way, a node which only cares about replaying transactions need not even decode the witness information.

In order to do this, we introduce two concepts: - A TxSeq, which represents the decoded structure of a sequence of transactions as represented in the encoded block; that is, with witnessing, metadata and other non-body parts split separately.

class (EraTx era, Eq (TxSeq era), Show (TxSeq era), EncCBORGroup (TxSeq era), DecCBOR (Annotator (TxSeq era))) ⇒ EraSegWits era where Source #

Indicates that an era supports segregated witnessing.

This class embodies an isomorphism between 'TxSeq era' and 'StrictSeq (Tx era)', witnessed by fromTxSeq and toTxSeq.

Rewards

data RewardType Source #

The staking rewards in Cardano are all either:

  • member rewards - rewards given to a registered stake credential which has delegated to a stake pool, or
  • leader rewards - rewards given to a registered stake pool (in particular, given to the stake credential in the stake pool registration certificate).

Most translations should be infallible (default instance), but we leave the door open for partial translations.

For a partial translation, override the default type to be () or a concrete error type.

class (Era era, Era (PreviousEra era)) ⇒ TranslateEra era f Source #

Translation of types between eras, e.g., from Shelley to Allegra.

When era is just a phantom type parameter, an empty standalone deriving can be used:

newtype Foo era = Foo Int

instance TranslateEra (Allegra c) Foo

Note that one could use DerivingAnyClass (deriving (TranslateEra (Allegra c))), but this would introduce an undesired coupling between the era-parametric type and (a) particular era(s). The intention is to have a module with orphan instances per era.

In most cases, the era parameter won't be phantom, and a manual instance will have to be written:

newtype Bar era = Bar (TxBody era)

instance CC.Crypto c => TranslateEra (Allegra c) Bar where
    translateEra ctxt = Bar <$> translateEra ctxt

-- With the following instance being in scope:
instance CC.Crypto c => TranslatEra (Allegra c) TxBody

Note: we use PreviousEra instead of NextEra as an era definitely knows its predecessor, but not necessarily its successor. Moreover, one could argue that it makes more sense to define the translation from era A to era B where era B is defined, than where era A is defined.

translateEraTranslateEra era f ⇒ TranslationContext era → f (PreviousEra era) → Except (TranslationError era f) (f era) Source #

Translate a type f parameterised by the era from an era to the era after it.

The translation is a given the translation context of era.

A default instance is provided for when the two types are Coercible.

translateEraMaybe ∷ (TranslateEra era f, TranslationError era f ~ ()) ⇒ TranslationContext era → f (PreviousEra era) → Maybe (f era) Source #

Variant of translateEra for when TranslationError is (), converting the result to a Maybe.

translateEra' ∷ (TranslateEra era f, TranslationError era f ~ Void) ⇒ TranslationContext era → f (PreviousEra era) → f era Source #

Variant of translateEra for when TranslationError is Void and the translation thus cannot fail.
