The book is exactly what it says it is.  &quot;Why Rust&quot;, an argument for Rust.  50+ pages. It&#x27;s a fun read, but not too useful. My own comment on Rust is that the borrow checker is brilliant, and we&#x27;ll see that again in other languages.  The type&#x2F;generic system picks up where C++ left off, and is very complex.  But that may get better as the mess settles down and gets better documentation.<p>We now need a &quot;programming in Rust&quot; book which is not by one of the Rust developers, who are too close to the design.
