#### http::icy_stream

Stream wrapper to process Shoutcast HTTP responses.

##### Synopsis

Defined in header `<boost/beast/_experimental/http/icy_stream.hpp>`

    template<
        class NextLayer>
    class icy_stream

##### Types

Name | Description
--- | ---
executor_type | The type of the executor associated with the object.
next_layer_type | The type of the next layer.

##### Member Functions

Name | Description
--- | ---
async_read_some | Start an asynchronous read.
async_write_some | Start an asynchronous write.
get_executor | Get the executor associated with the object.
icy_stream [constructor] | — Constructor.
next_layer | Get a reference to the next layer.
operator= |
read_some | Read some data from the stream.
write_some | Write some data to the stream.
~icy_stream [destructor] | Destructor.

##### Description

This wrapper replaces the word "ICY" in the first HTTP response received on the connection, with "HTTP/1.1". This allows the Beast parser to be used with Shoutcast servers, which send a non-standard HTTP message as the response. For asynchronous operations, the application must ensure that they are are all performed within the same implicit or explicit strand.

##### Thread Safety

Distinct objects:Safe.

Shared objects:Unsafe. The application must also ensure that all asynchronous operations are performed within the same implicit or explicit strand.

##### Example

To use the `icy_stream` template with an `tcp_stream` you would write:

    http::icy_stream<tcp_stream> is(ioc);

##### Template Parameters

Type | Description
--- | ---
`NextLayer` | The type representing the next layer, to which data will be read and written during operations. For synchronous operations, the type must support the SyncStream concept. For asynchronous operations, the type must support the AsyncStream concept.

##### Remarks

A stream object must not be moved or destroyed while there are pending asynchronous operations associated with it.
