Bridge between the optics and fused-effects ecosystems.

Provides combinators for the optics-based manipulation of state and context types provided by the fused-effects library, similar to those provided by optics-extra for mtl-based monad transformers.

fused-effects-optics

This package provides an interface to the optics library compatible with fused-effects. The combinators provided by optics-extra for operating in monadic contexts—gview, use, .=, &c.—rely on mtl for MonadState and MonadReader, which is not applicable to Reader and State effects.
