This library contains wrappers over autogenerated bindings for CSL and some types adapted from cardano-api and cardano-wallet. It is primarily used in cardano-transaction-lib.

This library presents Transaction and all its structural components as PureScript algebraic data types.

• Trivial types are implemented as newtypes over CSL (we use a vendored version for both nodejs & the browser, with GC added).
• Variant types are implemented as ADTs
• Records-like types are implemented as newtypes over PureScript records.

Here's what is included:

• EncodeAeson/DecodeAeson instances - no compatibility with CSL is maintained, because JSON encoders in CSL are partial
• AsCbor instances for types that are representable as binary
• Show, Eq, Ord, Generic instances where they make sense
• ToMetadata/FromMetadata and ToData/FromData typeclasses and some instances
• Some pretty-printing functions that render a TagSet from monad-logger.
• fromCsl / toCsl functions that lift values between CSL and purescript domains (only for types ported from CSL)

• Asset
• AssetClass
• PaymentPubKeyHash
• UtxoMap

• Semigroup instances for Value, ExUnits and Mint are unlawful (they unsafely throw on numeric overflows)
• No TransactionBuilder - for a framework to build transactions, see cardano-transaction-lib
• No Block, BlockHeader - these are not needed for an in-browser dApp.
• Recursion max-depth issues (JavaScript...)
