   9                 Instances for Binary for the types defined in the vector package,
  10                 making it easy to serialize vectors to and from disk. We use the
  11                 generic interface to vectors, so all vector types are supported.
  12                 Specific instances are provided for unboxed, boxed and storable
  13                 vectors.
  14
  15                 To serialize a vector:
  16
  17                 &gt; *Data.Vector.Binary&gt; let v = Data.Vector.fromList [1..10]
  18                 &gt; *Data.Vector.Binary&gt; v
  19                 &gt; fromList [1,2,3,4,5,6,7,8,9,10] :: Data.Vector.Vector
  20                 &gt; *Data.Vector.Binary&gt; encode v
  21                 &gt; Chunk "\NUL\NUL\NUL\NUL\NUL...\NUL\NUL\NUL\t\NUL\NUL\NUL\NUL\n" Empty
  22
  23                 Which you can in turn compress before writing to disk:
  24
  25                 &gt; compress . encode $ v
  26                 &gt; Chunk "\US\139\b\NUL\NUL\N...\229\240,\254:\NUL\NUL\NUL" Empty
