final class Resolver[+F[_], -I, +O] extends AnyRef

Resolver is one of the core abstractions of gql. The resolver class contains a collection of methods to aid comosition.

A Resolver forms an cats.arrow.Arrow; it can lift a function I => O. Resolver also forms cats.arrow.Choice which allows conditional branching.

Resolver also forms an cats.Applicative instance that sequences the operations.

Some methods are only available resolvers that have a certain shape. Consider taking a look at the companion object for more information.
