Module documentation for 0.2.5

Depends on 3 packages(full list with versions):
base, binary, vector

Instances for Binary for the types defined in the vector package, making it easy to serialize vectors to and from disk. We use the generic interface to vectors, so all vector types are supported. Specific instances are provided for unboxed, boxed and storable vectors.

To serialize a vector:

*Data.Vector.Binary> let v = Data.Vector.fromList [1..10]
*Data.Vector.Binary> v
fromList [1,2,3,4,5,6,7,8,9,10] :: Data.Vector.Vector
*Data.Vector.Binary> encode v
Chunk "\NUL\NUL\NUL\NUL\NUL...\NUL\NUL\NUL\t\NUL\NUL\NUL\NUL\n" Empty

Which you can in turn compress before writing to disk:

compress . encode $ v
Chunk "\US\139\b\NUL\NUL\N...\229\240,\254:\NUL\NUL\NUL" Empty

Try the cereal-vector package if you are looking for Data.Serialize instances.
