Provides stream-oriented handle functionality.

    class stream_handle :
      public windows::overlapped_handle

##### Types

Name | Description
--- | ---
executor_type | The type of the executor associated with the object.
lowest_layer_type | An overlapped_handle is always the lowest layer.
native_handle_type | The native representation of a handle.

##### Member Functions

Name | Description

assign | Assign an existing native handle to the handle.
async_read_some | Start an asynchronous read.
async_write_some | Start an asynchronous write.
cancel | Cancel all asynchronous operations associated with the handle.
close | Close the handle.
get_executor | Get the executor associated with the object.
get_io_context | (Deprecated: Use get_executor().) Get the io_context associated with the object.
get_io_service | (Deprecated: Use get_executor().) Get the io_context associated with the object.
is_open | Determine whether the handle is open.
lowest_layer | Get a reference to the lowest layer. Get a const reference to the lowest layer.
native_handle | Get the native handle representation.
operator= | Move-assign a stream_handle from another.
read_some | Read some data from the handle.
stream_handle | Construct a stream_handle without opening it. Construct a stream_handle on an existing native handle. Move-construct a stream_handle from another.
write_some | Write some data to the handle.

The `windows::stream_handle` class provides asynchronous and blocking stream-oriented handle functionality.
