# A simple round-robin data type

This package provide a simple data type wrap a round-robin table. so you can select resources(host, connection...) using round-robin fashion.

## Example

```haskell

import qualified Date.RoundRobin as RR

import qualified Network.HTTP.Client as HTTP

main :: IO ()

main = do

    reqs <- mapM HTTP.parseUrl ["http://foo.com", "http://bar.com", "http://qux.com"]

    proxyTable <- RR.newRoundRobin reqs

    manager <- HTTP.newManager HTTP.defaultManagerSettings

    ...

    -- maybe now you're inside a server service(a forked thread)

    -- use select to choose a request in round-robin fashion

        req <- RR.select proxyTable

        res <- HTTP.httpLbs req manager

        ...

```
