libghc-cereal-vector-dev 0.2.0.1-1build1 (arm64 binary) in ubuntu bionic

 Data.Serialize functions for Data.Vector.Generic vectors. Orphan
 instances are provided for Data.Vector, Data.Vector.Unboxed,
 Data.Vector.Storable, and Data.Vector.Primitive vectors.
 .
 The serialized format is an Int64 representing the length of the
 vector, followed by the Data.Serialized contents of each element.
 .
 Note that the functions in Data.Vector.Storable.UnsafeSerialize
 perform much better when serialization does not need to account for
 host endianness and word size.
 .
 This package provides a library for the Haskell programming language.
