    Type classes and other utilities used by fs2.

    Type Classes

    This package includes a minimal set of common functional type classes -- e.g., Functor, Applicative, Monad, Traverse -- along with some extensions that are more specialized like Suspendable, Catchable, Effect, and Async.

    Infix syntax is provided for all of these type classes by the fs2.util.syntax object, which is used by adding import fs2.util.syntax._. The infix syntax has no runtime cost. The type classes generally do not define many derived methods (with the exception of Async). Instead, derived methods are defined soley infix. For example, Monad does not define flatten but monad infix syntax does.

    Note that these type classes are intentionally minimal. Providing a general purpose set of functional structures is not a goal of FS2.
