Thrift for Haskell

Meta has open-sourced hsthrift, providing full Thrift support for Haskell projects. This enables Haskell clients and servers to communicate with other Thrift-based systems, leveraging fbthrift's efficient foundation. The toolchain includes a Haskell Thrift compiler that generates Haskell code for cross-service communication, with advanced features like required symbol pruning, AST transformations with formatting preservation (exactprint), typechecker plugins for custom rules, and splicing for typeclass instances. This release aims to facilitate the building of efficient distributed systems in Haskell and integration into existing Thrift ecosystems.
