class (EraSegWits era, ShelleyEraTxBody era, Split (Value era), ScriptClass era, EraPParams era, MinGenTxout era, Default (StashedAVVMAddresses era)) ⇒ EraGen era where Source #
Minimal complete definition
genGenesisValue, genEraTxBody, genEraAuxiliaryData, updateEraTxBody, genEraPParamsUpdate, genEraPParams, genEraTxWits
Methods
genGenesisValue ∷ GenEnv era → Gen (Value era) Source #
Generate a genesis value for the Era
genEraTwoPhase3Arg ∷ [TwoPhase3ArgInfo era] Source #
A list of three-phase scripts that can be chosen for payment when building a transaction
genEraTwoPhase2Arg ∷ [TwoPhase2ArgInfo era] Source #
A list of two-phase scripts that can be chosen for Delegating, Minting, or Rewarding when building a transaction
genEraTxBody ∷ GenEnv era → UTxO era → PParams era → SlotNo → Set TxIn → StrictSeq (TxOut era) → StrictSeq (TxCert era) → Withdrawals → Coin → StrictMaybe (Update era) → StrictMaybe TxAuxDataHash → Gen (TxBody era, [Script era]) Source #
Given some pre-generated data, generate an era-specific TxBody, and a list of additional scripts for eras that sometimes require additional script witnessing.
genEraAuxiliaryData ∷ Constants → Gen (StrictMaybe (TxAuxData era)) Source #
Generate era-specific auxiliary data
Arguments
| ∷ UTxO era | |
| → PParams era | |
| → TxWits era | |
| → TxBody era | |
| → Coin | |
| → Set TxIn | This overrides the existing TxFee |
| → TxOut era | This is to be Unioned with the existing TxIn |
| → TxBody era | This is to be Appended to the end of the existing TxOut |
Update an era-specific TxBody
addInputs ∷ TxBody era → Set TxIn → TxBody era Source #
Union the TxIn with the existing TxIn in the TxBody
genEraPParamsUpdate ∷ Constants → PParams era → Gen (PParamsUpdate era) Source #
genEraPParams ∷ Constants → Gen (PParams era) Source #
genEraTxWits ∷ (UTxO era, TxBody era, ScriptInfo era) → Set (WitVKey 'Witness) → Map ScriptHash (Script era) → TxWits era Source #
genEraGoodTxOut ∷ TxOut era → Bool Source #
constructTx ∷ TxBody era → TxWits era → StrictMaybe (TxAuxData era) → Tx era Source #
Construct a transaction given its constituent parts.
genEraScriptCost ∷ PParams era → Script era → Coin Source #
compute the delta cost of an additional script on per Era basis.
genEraDone ∷ UTxO era → PParams era → Tx era → Gen (Tx era) Source #
A final opportunity to tweak things when the generator is done. Possible uses 1) Add tracing when debugging on a per Era basis
genEraTweakBlock ∷ PParams era → Seq (Tx era) → Gen (Seq (Tx era)) Source #
A final opportunity to tweak things at the block level. Possible uses
2) Run a test that might decide to discard the test, because we got unlucky, and a rare unfixible condition has occurred.
hasFailedScripts ∷ Tx era → Bool Source #

someKeyPairs ∷ Constants → (Int, Int) → Gen KeyPairs Source #
Select between _lower_ and _upper_ keys from keyPairs
allScripts ∷ ∀ era. EraGen era ⇒ Constants → [(Script era, Script era)] Source #
A list of all possible kinds of scripts in the current Era.

mkDummyHash ∷ (HashAlgorithm h, EncCBOR a) ⇒ a → Hash h b Source #
It is possible to use a hash of a binary representation of any type as a source of randomness, since hash value by its definiteion is uniformly distributed.
