After a hardfork, the era from which we hardfork from gets deprecated and after deprecation period, gets removed. During deprecation period, consumers of cardano-api should update their codebase to the mainnet era.

Constructors

BabbageEra :: Era BabbageEra	The era currently active on Cardano's mainnet.
ConwayEra :: Era ConwayEra	The upcoming era in development.

data Some (f :: k -> Type) where Source #

An existential wrapper for types of kind k -> Types. Use it to hold any era e.g. Some Era. One can then bring the era witness back into scope for example using this pattern: anyEra = Some ConwayEra -- then later in the code Some era <- pure anyEra obtainCommonConstraints era foo

type family LedgerEra era = (r :: Type) | r -> era where ... Source #

Users typically interact with the latest features on the mainnet or experiment with features from the upcoming era. Hence, the protocol versions are limited to the current mainnet era and the next era (upcoming era).

How to deprecate an era

Add DEPRECATED pragma to the era type tag and the era constructor at the same time: {-# DEPRECATED BabbageEra "BabbageEra no longer supported, use ConwayEra" #-} data BabbageEra
Update haddock for the constructor of the deprecated era, mentioning deprecation.

data Era era where
  {-# DEPRECATED BabbageEra "BabbageEra no longer supported, use ConwayEra" #-}
  BabbageEra :: Era BabbageEra
  -- | The era currently active on Cardano's mainnet.
  ConwayEra :: Era ConwayEra

Add new IsEra instance and update the deprecated era instance to produce a compile-time error: @ instance TypeError ('Text "IsEra BabbageEra: Deprecated. Update to ConwayEra") => IsEra BabbageEra where useEra = error "unreachable"

instance IsEra ConwayEra where useEra = ConwayEra @
