Buffered stream helper trait.  

Wraps the asynchronous generator methods with asynchronous promise-based methods


## Method list:
* `getReadBuffer(int $length): \Amp\Promise`
* `getWriteBuffer(int $length, string $append): \Amp\Promise`

## Methods:
### `getReadBuffer(int $length): \Amp\Promise`

Get read buffer asynchronously.


Parameters:
* `$length`: `int` Length of payload, as detected by this layer  


#### See also: 
* `\Amp\Promise`




### `getWriteBuffer(int $length, string $append): \Amp\Promise`

Get write buffer asynchronously.


Parameters:
* `$length`: `int` Total length of data that is going to be piped in the buffer  
* `$append`: `string` Data to append after entire buffer is written  


#### See also: 
* `\Amp\Promise`
