Documentation

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.

Constructors

MultiUpdate

If set, the database will update all matching objects in the collection. Otherwise only updates first matching doc
