Synopsis

MongoDB re-exports

genObjectId :: IO ObjectId #

Create a fresh ObjectId

fval :: (forall a. Val a => a -> b) -> Value -> b #

Apply generic function to typed value

(=:) :: Val v => Label -> v -> Field infix 0 #

Field with given label and typed value

data ObjectId #

A BSON ObjectID is a 12-byte value consisting of a 4-byte timestamp (seconds since epoch), a 3-byte machine id, a 2-byte process id, and a 3-byte counter. Note that the timestamp and counter fields must be stored big endian unlike the rest of BSON. This is because they are compared byte-by-byte and we want to ensure a mostly increasing order.

Type aliases

We created type aliases for specific Mongo types. These include: Action, Collection, Database, Document, Field, Label, Query, Selector, Val, and Value.

type MongoAction = Action Source #

type MongoCollection = Collection Source #

type MongoDatabase = Database Source #

type MongoDocument = Document Source #

type MongoField = Field Source #

type MongoLabel = Label Source #

type MongoQuery = Query Source #

type MongoValue = Value Source #

type MongoVal = Val Source #

Pattern synonyms

We created pattern synonyms for the MongoValue constructors.

pattern MongoArray :: [Value] -> MongoValue Source #

pattern MongoBin :: Binary -> MongoValue Source #

pattern MongoBool :: Bool -> MongoValue Source #

pattern MongoDoc :: Document -> MongoValue Source #

pattern MongoFloat :: Double -> MongoValue Source #

pattern MongoFun :: Function -> MongoValue Source #

pattern MongoInt32 :: Int32 -> MongoValue Source #

pattern MongoInt64 :: Int64 -> MongoValue Source #

pattern MongoJavaScr :: Javascript -> MongoValue Source #

pattern MongoMd5 :: MD5 -> MongoValue Source #

pattern MongoMinMax :: MinMaxKey -> MongoValue Source #

pattern MongoNull :: MongoValue Source #

pattern MongoObjId :: ObjectId -> MongoValue Source #

pattern MongoRegEx :: Regex -> MongoValue Source #

pattern MongoStamp :: MongoStamp -> MongoValue Source #

pattern MongoString :: Text -> MongoValue Source #

pattern MongoSym :: Symbol -> MongoValue Source #

pattern MongoUserDef :: UserDefined -> MongoValue Source #

pattern MongoUTC :: UTCTime -> MongoValue Source #

pattern MongoUuid :: UUID -> MongoValue Source #

Function aliases

We created aliases for specific Mongo functions. These include: failed, insert_, nModified, select, and updateMany.

mongoFailed :: WriteResult -> Bool Source #

mongoInsert_ :: MonadIO m => MongoCollection -> MongoDocument -> MongoAction m () Source #

mongoModified :: WriteResult -> Maybe Int Source #

mongoSelect :: MongoSelector -> MongoCollection -> MongoQuery Source #

mongoUpdateMany :: MonadIO m => MongoCollection -> [(MongoSelector, MongoDocument, [UpdateOption])] -> MongoAction m WriteResult Source #

Operators aliases

We created aliases for specific Mongo operators. These include: (>=:), (>:), (<=:), (<:), (<-:), (!<-:), and (!=:).

(>=:) :: MongoVal v => MongoLabel -> v -> MongoField Source #

(>:) :: MongoVal v => MongoLabel -> v -> MongoField Source #

(<=:) :: MongoVal v => MongoLabel -> v -> MongoField Source #

(<:) :: MongoVal v => MongoLabel -> v -> MongoField Source #

(<-:) :: MongoVal v => MongoLabel -> [v] -> MongoField Source #

(!<-:) :: MongoVal v => MongoLabel -> [v] -> MongoField Source #

(!=:) :: MongoVal v => MongoLabel -> v -> MongoField Source #
