data Matcher ext

A value constructed using qq that attempts to match a JSON document.

Constructors

Hole (Maybe HoleSig) (Maybe Text)

Optionally typed, optionally named _hole. If a type is provided, the _hole only matches those values that have that type. If a name is provided, the matched value is returned to the user.

Number Scientific

Object (Object ext)

Ext ext

External values spliced into a Matcher using the `#{}` syntax

Instances

Functor Matcher

Defined in Aeson.Match.QQ.Internal.Value

Methods

fmap :: (a -> b) -> Matcher a -> Matcher b

(<$) :: a -> Matcher b -> Matcher a

ext ~ Exp => Lift (Matcher ext :: Type)

Convert `Matcher Exp` to `Matcher Value`. This uses a roundabout way to get Value from toEncoding to avoid calling toJSON which may be undefined for some datatypes.

lift :: Quote m => Matcher ext -> m Exp

liftTyped :: forall (m :: Type -> Type). Quote m => Matcher ext -> Code m (Matcher ext)
