|
Rust is a new systems programming language that combines the performance and |
|
low-level control of C and C++ with memory safety and thread safety. Rust's |
|
modern, flexible types ensure your program is free of null pointer |
|
dereferences, double frees, dangling pointers, and similar bugs, all at |
|
compile time, without runtime overhead. In multi-threaded code, Rust catches |
|
data races at compile time, making concurrency much easier to use.</p> |

|
<p>First off, this is not a book for <em>learning</em> Rust: This is a Reference Book. A |
|
good one at it, but not for learning.</p> |
|
<p>My inclination to learn Rust is how it deals with errors (it's <code>Result</code> enum), |
|
something that most languages seem to drop out of context or accept some |
|
"catch all" which let developers ignore such errors. Rust doesn't; you |
|
<b>have</b> to deal with errors.</p> |
|
<p>And, in such small thing, which I thought it was very simple and |
|
straightforward... is not. The <code>Err</code> part can be very complex, specially if |
|
you want to keep in line with the rest of the system. Which is good.</p> |
|
<p>Although a good book, it's not great. The explanation for generics is very |
|
convoluted and complex and doesn't help grasping the whole context -- maybe |
|
it's easier if you're already working with a language that has generics. And |
|
then, when you are almost getting how they work, they throw lifetimes in it |
|
and the confusion grows. </p> |
|
<p>Several topics are started and then become "beyond the scope of this book". So |
|
it just brushes some pointers at it and then completely forget about it. I, |
|
personally, would drop some of those -- it could mention that they exist -- |
|
and expanding for not being "beyond the scope of this book".</p> |
