FieldOptic s is a type of optics that points a field/constructor named s.

The yielding fields can be Lenses for Records and Prisms for Variants.

FieldOptic "foo" = Lookup xs "foo" a => Lens' (Record xs) a
FieldOptic "foo" = Lookup xs "foo" a => Prism' (Variant xs) a

FieldOptics can be generated using mkField defined in the Data.Extensible.TH module.

type FieldName k = Optic' (LabelPhantom k) Proxy (Inextensible '[k :> ()] (Field Proxy)) () Source #

When you see this type as an argument, it expects a FieldLens. This type is used to resolve the name of the field internally.
