servant-client-core

HTTP-client-agnostic client functions for servant APIs.

This library should mainly be of interest to backend- and combinator-writers.

For backend-writers

If you are creating a new backend, you'll need to:

1. Define a RunClient instance for your datatype (call it MyMonad)
2. Define a ClientLike instance. This will look like:

instance ClientLike (MyMonad a) (MyMonad a) where
  mkClient = id

3. Re-export the module Servant.Client.Core.Reexport so that your end-users can be blissfully unaware of 'servant-client-core', and so each backend-package comes closer to the warm hearth of the drop-in-replacement equivalence class.

For combinator-writers

You'll need to define a new HasClient instance for your combinator. There are plenty of examples to guide you in the HasClient module.
