After a hard fork takes place, the era on mainnet before the hard fork is deprecated and, after a deprecation period, removed from cardano-api. During the deprecation period, cardano-api users should update their codebase to the new mainnet era.

Constructors

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

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

An existential wrapper for types of kind k -> Type. It can hold any era, for example, Some Era. The era witness can be brought 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. Therefore, protocol versions are limited to the current mainnet era and the next (upcoming) era.

LedgerEra BabbageEra = Babbage

Deprecated: Use convert instead.

How to deprecate an era:

Add the DEPRECATED pragma to the era type tag and constructor at the same time:

{-# DEPRECATED BabbageEra "BabbageEra no longer supported, use ConwayEra" #-}
data BabbageEra

Update the Haddock documentation for the constructor of the deprecated era, mentioning the 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 a 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
