I'm still having problems with the uvector package.
I have an IntMap (UArr xxx) data type, and I want to serialize it to
disk, in binary format.
I'm using the uvector package from
The problem is with missing instance declarations, for Hyperstrict data
type and Data.Array.Vector.UArr.UPrim.
For the former, the instance is simple, but for the latter I have no
idea about what to do.
The full error message (GHC 6.8.2):
No instance for (uvector-0.2:Data.Array.Vector.UArr.UPrim
arising from a use of `encode' at bin/process-data-1.hs:72:18-36
add an instance declaration for
(Word32 uvector-0.2:Data.Array.Vector.Prim.Hyperstrict.:*: Word8))
Thanks Manlio Perillo
