libghc-cereal-dev 0.5.8.3-1build1 (riscv64 binary) in ubuntu lunar

 A binary serialization library, similar to binary, that introduces an isolate
 primitive for parser isolation, and replaces the asynchronous errors with a
 user-handleable Either type. Similar to binary in performance, but uses a
 strict ByteString instead of a lazy ByteString, thus restricting it to
 operating on finite inputs.

 This package provides a library for the Haskell programming language.
