Dictionary of one key-value pair. O(1). Is the dictionary empty? O(n)). Is the key a member of the dictionary? O(n)/. Lookup the value at a key in the dictionary. O(n + m)8. Merge two dictionaries by taking pair from both given # dictionaries. Dublicated keys are not filtered. O(n).3 Map a function over all values in the dictionary. O(n). Map each key/*value pair to a monoid and fold resulting  sequnce using 9. O(n)'. Build a dictionary from a list of key/value pairs where " the keys are in ascending order. O(n)).

Using the same FileInfo datatype the  $ function instance looks like:    instance " FileInfo where  $ = 6 $ do  FileInfo 2 "length"  5 "md5sum"  4 "path"  5 "tags" The reqKey7 is used to extract required key  if lookup is failed ! then whole destructuring fail.

Suppose we have we following datatype we want to  serialize:    data FileInfo = FileInfo  { fileLength :: Integer & , fileMD5sum :: Maybe ByteString  , filePath :: [ByteString]  , fileTags :: Maybe [Text] ! } deriving (Show, Read, Eq) We need to make  instance " FileInfo, though we don't want  to check the both A%s manually. The more declarative and  convenient way to define the # method is to use  dictionary builders:    instance " FileInfo where  # FileInfo {..} = * $  "length" ' fileLength  ) "md5sum" ( fileMD5sum  ) "path" ' filePath  ) "tags" ( fileTags  ) + BNOTE: the list of pairs MUST be sorted lexicographically by keys,  like so: "length" @ "md5sum" @ "path" @ "tags" "@This class is used to define new datatypes that could be easily " serialized using bencode format.
