objectsTable :: Exp Table

blobsTable :: Exp Table

secretsTable :: Exp Table

patchesTable :: Exp Table

snapshotsTable :: Exp Table

sessionsTable :: Exp Table

primaryKeyField :: Text

The primary key in all our documents is the default "id".

primaryKeyFieldE :: Exp Text

Expression which represents the primary key field.

objectFieldE :: IsDatum a => Text -> Exp Object -> Exp a

Expression which represents the value of a field inside of an Object.

objectFieldEqE :: ToDatum a => Text -> a -> Exp Object -> Exp Bool

True if the object field matches the given value.

primaryKeyEqE :: Text -> Exp Object -> Exp Bool

True if the object's primary key matches the given string.

headE :: (IsSequence a, IsDatum r) => Exp a -> Exp r

Take the first item out of a sequence. Beware that this throws an error when the sequence is empty.

limitE :: IsSequence s => Int -> Exp s -> Exp s

Limit a sequence to the first n items.

mkBounds :: ObjectId -> Int -> Int -> (Bound, Bound)

mkBound :: ObjectId -> Int -> Bound
