purescript-cardano-types

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 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)

Types not from CSL:

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...)
