You can see an example in biofasta:
https://github.com/BioHaskell/biofasta/blob/master/src/Bio/Sequence/Fasta.hs
on line 31:
import Bio.Core.Sequence
then lines 37-44:
data Sequence = Seq SeqLabel SeqData (Maybe QualData)
deriving (Show, Eq)
instance BioSeq Sequence where
seqid (Seq lab seq mqual) = SeqLabel {unSL = B.takeWhile (/= '
') $ unSL lab}
seqheader (Seq lab seq mqual) = lab
seqdata (Seq lab seq mqual) = seq
seqlength (Seq lab seq mqual) = Offset {unOff = B.length $ unSD seq}
The BioSeq typeclass that is used above comes from Bio.Core.Sequence:
http://malde.org/~ketil/biohaskell/biocore/src/Bio/Core/Sequence.hs
-- | The 'BioSeq' class models sequence data, and any data object that
-- represents a biological sequence should implement it.
class BioSeq s where
seqid :: s -> SeqLabel -- ^ Sequence identifier (typically first
word of the header)
seqid = seqlabel
seqheader :: s -> SeqLabel -- ^ Sequence header (may contain
whitespace), by convention the
-- first word matches the 'seqid'
seqheader = seqlabel
seqdata :: s -> SeqData -- ^ Sequence data
seqlength :: s -> Offset -- ^ Sequence length
