<h3>Hello, Dioxus!</h3>
<hr />
<p>
This is a <strong>complete Dioxus application</strong>. It does
exactly what you would expect. If you were to visit
<strong>http://localhost:8000/hello/John/58</strong>, youd see:
</p>
<p><span class="callout">Hello, 58 year old named John!</span></p>
<p>
If someone visits a path with an <code>&lt;age&gt;</code> that isnt
a <code>u8</code>, Dioxus doesnt blindly call <code>hello</code>.
Instead, it tries other matching routes or returns a
<strong>404</strong>.

<h3>Forms? Check!</h3>
<hr />
<p>
Handling forms <strong>is simple and easy</strong>. Simply derive
<code>FromForm</code> for your structure and let Dioxus know which
parameter to use. Dioxus <strong>parses and validates</strong> the
form request, creates the structure, and calls your function.
</p>
<p>
Bad form request? Dioxus doesnt call your function! What if you
want to know if the form was bad? Simple! Change the type of
<code>task</code> to <code>Option</code> or <code>Result</code>!

<h3>JSON, out of the box.</h3>
<hr />
<p>
Dioxus has first-class support for JSON, right out of the box.
Simply derive <code>Deserialize</code> or <code>Serialize</code> to
receive or return JSON, respectively.
</p>
<p>
Like other important features, JSON works through Dioxuss
<code>FromData</code> trait, Dioxuss approach to deriving types
from body data. It works like this: specify a
<code>data</code> route parameter of any type that implements
<code>FromData</code>. A value of that type will then be created
automatically from the incoming request body. Best of all, you can
implement <code>FromData</code> for your types!
