Documentation
Class for translating to and from Datum.
There are instances for the direct Datum field types.
d_put (1::Int32) == Int32 1 d_put (1::Int64) == Int64 1 d_put (1::Float) == Float 1 d_put (1::Double) == Double 1 d_put (Char8.pack "str") == ASCII_String (Char8.pack "str") d_put (Lazy.pack [37,37]) == Blob (blob_pack [37,37]) d_put (MIDI 0 0 0 0) == Midi (MIDI 0 0 0 0)
There are also instances for standard Haskell types.
d_put (1::Int) == Int64 1 d_put (1::Integer) == Int64 1
