|
<p>The shortest and simpler way to describe this book is this:</p>
|
||
|
|
<pre data-lang="rust" style="background-color:#2b303b;color:#c0c5ce;" class="language-rust "><code class="language-rust" data-lang="rust"><span style="color:#b48ead;">let mut</span><span> a = </span><span style="color:#d08770;">1</span><span>;
|
||
|
|
</span><span>a = a + </span><span style="color:#d08770;">1</span><span>;
|
||
|
|
</span><span style="color:#65737e;">// increase a
|
||
|
|
</span></code></pre>
|
||
|
|
<p>Sure, increasing <code>a</code> may seem interesting, but where the heck is the
|
||
|
|
explanation on why you're increasing a?</p>
|
||
|
|
<p>The long version is this: this is an exact representation of what a Packt book
|
||
|
|
is. There are a bunch of grammatical errors from the half of the book to the
|
||
|
|
end, which should've picked by the editor; there are a bunch of weird
|
||
|
|
explanations and the incredible tendency of use a different package on each
|
||
|
|
project (one project uses Hyper, the other Rocket, the other Actix-Web) which
|
||
|
|
should've been picked by the reviewer; the whole book have a bunch of text
|
||
|
|
saying what the code is doing, but not why it was designed that way.</p>
|
||
|
|
<p>So the whole thing feels rushed and without thought.</p>
|
||
|
|
<p>The "change package on each discussion" is also damming: you never really got
|
||
|
|
deep into a package, understanding its ins and outs, because it keeps changing
|
||
|
|
all the time (logs is another thing that keeps changing all the time in the
|
||
|
|
code, which seems really weird when you want to have a fleet of microservices
|
||
|
|
-- why would you use different packages on all of them; yes, you can do this
|
||
|
|
due the nature of microservices, but does it make sense?).</p>
|
||
|
|
<p>Also, no code is shown in completion. The book uses snippets all around instead
|
||
|
|
of showing everything. The full code is available on Github, but that means you
|
||
|
|
need to keep two sources open at the same time: one in the book, to follow
|
||
|
|
whatever the author is showing and the source code to understand where each
|
||
|
|
thing fall in the big picture.</p>
|
||
|
|
<p>Those two last points could be easily solved by starting with a simple code
|
||
|
|
(say, the Hyper that says "Hello world") and then, slowly, refactor it to reach
|
||
|
|
a fully asynchronous code, showing the full code with each refactor
|
||
|
|
highlighted.</p>
|
||
|
|
<p>Maybe this will be a good book in the 3rd edition.</p>
