# Book Goals and Style
|
||
|
|
|
||
|
|
So, what's this book actually gonna teach you?
|
||
|
|
|
||
|
|
I'm _not_ gonna tell you how to use a crate that already exists.
|
||
|
|
|
||
|
|
Don't get me wrong, there _is_ a [gba](https://crates.io/crates/gba) crate, and
|
||
|
|
it's on crates.io and all that jazz.
|
||
|
|
|
||
|
|
However, unlike most crates that come with a tutorial book, I don't want to just
|
||
|
|
teach you how to use the crate. What I want is to teach you what you need to
|
||
|
|
know so that you could build the crate yourself, from scratch, if it didn't
|
||
|
|
already exist for you. Let's call it the [Handmade
|
||
|
|
Hero](https://handmadehero.org/) school of design. Much more than you might find
|
||
|
|
in other Rust crate books, I'll be attempting to show a lot of the _why_ in
|
||
|
|
addition to just the _how_. Once you know how to do it all on your own, you can
|
||
|
|
decide for yourself if the `gba` crate does it well, or if you think you can
|
||
|
|
come up with something that suits your needs better.
|
||
|
|
|
||
|
|
Overall the book is sorted for easy review once you're trying to program
|
||
|
|
something, and the GBA has a few interconnected concepts, so some parts of the
|
||
|
|
book end up having to refer you to portions that you haven't read yet. The
|
||
|
|
chapters and sections are sorted so that _minimal_ future references are
|
||
|
|
required, but it's unavoidable.
|
||
|
|
|
||
|
|
The actual "tutorial order" of the book is the
|
||
|
|
[Examples](../05-examples/00-index.md) chapter. Each section of that chapter
|
||
|
|
breaks down one of the provided examples in the [examples
|
||
|
|
directory](https://github.com/rust-console/gba/tree/master/examples) of the
|
||
|
|
repository. We go over what sections of the book you'll need to have read for
|
||
|
|
the example code to make sense, and also how we apply the general concepts
|
||
|
|
described in the book to the specific example cases.
