Description

This module provides Template Haskell helper functions for generating type-safe service/session wrappers for amazonka.

Synopsis

wrapAWSService :: Name -> String -> String -> Q [Dec]

Documentation

wrapAWSService Source #

Arguments

:: Name	Name of the amazonka `Service` value to wrap
-> String	Name of the service type to generate
-> String	Name of the session type to generate
-> Q [Dec]	Declarations for splicing into source file

Generates type-safe AWS service and session wrapper types for use with connect and withAWS functions

Example top-level invocation:

{-# LANGUAGE TemplateHaskell #-}
{-# LANGUAGE TypeFamilies #-}

module MyApp.Services
    ( DynamoDBService
    , DynamoDBSession
    , dynamoDBService
    ) where

import Network.AWS.DynamoDB (dynamoDB)
import Network.AWS.Easy (wrapAWSService)

wrapAWSService 'dynamoDB "DynamoDBService" "DynamoDBSession"

This will generate boilerplate like the following:

data DynamoDBService = DynamoDBService Service

data DynamoDBSession = DynamoDBSession Session

instance ServiceClass DynamoDBService where
    type TypedSession DynamoDBService = DynamoDBSession
    rawService (DynamoDBService x) = x
    wrappedSession = DynamoDBSession

instance SessionClass DynamoDBSession where
    rawSession (DynamoDBSession x) = x

dynamoDBService :: DynamoDBService
dynamoDBService = DynamoDBService dynamoDB
