 ## Single Request Utils
 
-### `handleResult`
+### `RequestCubit`
 
-`handleResult` is a client-specific method needed for handling the API response. It can be defined once and used repeatedly as a mixin.
+`RequestCubit` is used to execute a single API request. It has four generic arguments: TRes, TData, TOut and TError. TRes specifies what the request returns, TData specifies what is kept in TRes as response body, TOut determines which model we want to emit as data in the state, TError defines error's type. In the example below, `HttpRequestCubit` provides the generic http implementation that can be used while defining all needed `RequestCubits`.
 
 ```dart
-mixin HandleResult<TOut>
-    on RequestCubit<http.Response, String, TOut, int> {
+/// Base class for http request cubits.
+abstract class HttpRequestCubit<TOut>
+    extends RequestCubit<http.Response, String, TOut, int> {

-  // and return the result on success or call handleError on failure.

-`run` is a client-specific method that performs the pre-request and returns the new state. It can be defined once and used repeatedly as a mixin.
