<p>An <code>IOHandler</code> is an object that has a <code>save</code> method of the proper
signature defined. The <code>save</code> method manages the storing or
transmission of serialized data ("artifacts") that represent the
model's topology and weights onto or via a specific medium, such as
file downloads, local storage, IndexedDB in the web browser and HTTP
requests to a server. TensorFlow.js provides <code>IOHandler</code>
implementations for a number of frequently used saving mediums, such as
<code>tf.io.browserDownloads</code> and <code>tf.io.browserLocalStorage</code>. See <code>tf.io</code>
for more details.</p>
<p>This method also allows you to refer to certain types of <code>IOHandler</code>s
as URL-like string shortcuts, such as 'localstorage://' and
'indexeddb://'.</p>
