Cardano.Ledger.Shelley.API.Validation

Description

Interface to the block validation and chain extension logic in the Shelley API.

Documentation

class (STS (EraRule "TICK" era), BaseM (EraRule "TICK" era) ~ ShelleyBase, Environment (EraRule "TICK" era) ~ (), State (EraRule "TICK" era) ~ NewEpochState era, Signal (EraRule "TICK" era) ~ SlotNo, STS (EraRule "BBODY" era), BaseM (EraRule "BBODY" era) ~ ShelleyBase, Environment (EraRule "BBODY" era) ~ BbodyEnv era, State (EraRule "BBODY" era) ~ ShelleyBbodyState era, Signal (EraRule "BBODY" era) ~ Block BHeaderView era, EncCBORGroup (TxSeq era), State (EraRule "LEDGERS" era) ~ LedgerState era) ⇒ ApplyBlock era where Source #

Methods

applyTickOpts ∷ ApplySTSOpts ep → Globals → NewEpochState era → SlotNo → EventReturnType ep (EraRule "TICK" era) (NewEpochState era) Source #

Apply the header level ledger transition.

This handles checks and updates that happen on a slot tick, as well as a few header level checks, such as size constraints.

applyBlockOpts ∷ ∀ ep m. (EventReturnTypeRep ep, MonadError (BlockTransitionError era) m) ⇒ ApplySTSOpts ep → Globals → NewEpochState era → Block BHeaderView era → m (EventReturnType ep (EraRule "BBODY" era) (NewEpochState era)) Source #

Apply the block level ledger transition.

default applyBlockOpts ∷ ∀ ep m. (EventReturnTypeRep ep, MonadError (BlockTransitionError era) m, EraGov era) ⇒ ApplySTSOpts ep → Globals → NewEpochState era → Block BHeaderView era → m (EventReturnType ep (EraRule "BBODY" era) (NewEpochState era)) Source #

reapplyBlock ∷ Globals → NewEpochState era → Block BHeaderView era → NewEpochState era Source #

Re-apply a ledger block to the same state it has been applied to before.

This function does no validation of whether the block applies successfully; the caller implicitly guarantees that they have previously called applyBlockTransition on the same block and that this was successful.
