============

Harness RethinkDB Callbacks with ECMAScript 6 Generators

## Installation

    $ npm install rethinkdb-co

## Example

```javascript

var rco = require('rethinkdb-co');

var r   = require('rethinkdb');

var co  = require('co');

var query = r.tableList();

co(function *() {

  // pause and wait for connection

  var connection = yield rco.connect();

  // pause and wait for result

  var result = yield rco.run(query);

  console.log('result', result);

  // disconnect

  yield rco.disconnect();

})();

```

## With koa-rethinkdb

```javascript

var rethinkdbPool = require('koa-rethinkdb');

var rco           = require('rethinkdb-co');

var r             = require('rethinkdb');

app.use(rethinkdbPool(options));

app.use(function *(next) {

    // get the list of table

    var query1 = r.db('test').tableList();

    var list = yield rco.run(query1);

    // select a few documents

    var query2 = r.db('test').table('foobar').limit(10);

    result = yield rco.runf(query2);

    yield next;

    // connections are released back to the pool.

});

````

## methond: run

Return the result you would expect from rethinkdb client.

## methond: runf

If the query returns a cursor, run `cursor.toArray()` for you, since that's probably what you want.
