+ * __useDeleteOneRoleMutation__
+ *
+ * To run a mutation, you first call `useDeleteOneRoleMutation` within a React component and pass it any options that fit your needs.
+ * When your component renders, `useDeleteOneRoleMutation` returns a tuple that includes:
+ * - A mutate function that you can call at any time to execute the mutation
+ * - An object with fields that represent the current status of the mutation's execution
+ *
+ * @param baseOptions options that will be passed into the mutation, supported options are listed on: https://www.apollographql.com/docs/react/api/react-hooks/#options-2;
+ *
+ * @example
+ * const [deleteOneRoleMutation, { data, loading, error }] = useDeleteOneRoleMutation({
+ *   variables: {
+ *      roleId: // value for 'roleId'
+ *   },
+ * });
