generic-lens-core: Generically derive traversals, lenses and prisms.

[ bsd3, generics, lens, library, records ] [ Propose Tags ] [ Report a vulnerability ]

This library uses GHC.Generics to derive efficient optics (traversals, lenses and prisms) for algebraic data types in a type-directed way, with a focus on good type inference and error messages when possible.

This package is the shared internal logic of the generic-lens and generic-optics libraries.
