## Completion
|
||||||
|
|
||||||
|
Rustlings isn't done; there are a couple of sections that are very experimental and don't have proper documentation. These include:
|
||||||
|
|
||||||
|
- Errors (`exercises/errors/`)
|
||||||
|
- Option (`exercises/option/`)
|
||||||
|
- Result (`exercises/result/`)
|
||||||
|
- Move Semantics (could still be improved, `exercises/move_semantics/`)
|
||||||
|
|
||||||
|
Additionally, we could use exercises on a couple of topics:
|
||||||
|
|
||||||
|
- Structs
|
||||||
|
- Better ownership stuff
|
||||||
|
- `impl`
|
||||||
|
- ??? probably more
|
||||||
|
|
||||||
|
If you are interested in improving or adding new ones, please feel free to contribute! Read on for more information :)

Thanks for installing Rustlings!
|
||||||
|
|
||||||
|
Is this your first time? Don't worry, Rustlings was made for beginners! We are
|
||||||
|
going to teach you a lot of things about Rust, but before we can get
|
||||||
|
started, here's a couple of notes about how Rustlings operates:
|
||||||
|
|
||||||
|
1. The central concept behind Rustlings is that you solve exercises. These
|
||||||
|
exercises usually have some sort of syntax error in them, which will cause
|
||||||
|
them to fail compilation or testing. Sometimes there's a logic error instead
|
||||||
|
of a syntax error. No matter what error, it's your job to find it and fix it!
|
||||||
|
You'll know when you fixed it because then, the exercise will compile and
|
||||||
|
Rustlings will be able to move on to the next exercise.
|
||||||
|
2. If you run Rustlings in watch mode (which we recommend), it'll automatically
|
||||||
|
start with the first exercise. Don't get confused by an error message popping
|
||||||
|
up as soon as you run Rustlings! This is part of the exercise that you're
|
||||||
|
supposed to solve, so open the exercise file in an editor and start your
|
||||||
|
detective work!
|
||||||
|
3. If you're stuck on an exercise, there is a helpful hint you can view by typing
|
||||||
|
'hint' (in watch mode), or running `rustlings hint myexercise`.
|
||||||
|
4. If an exercise doesn't make sense to you, feel free to open an issue on GitHub!
|
||||||
|
(https://github.com/rust-lang/rustlings/issues/new). We look at every issue,
|
||||||
|
and sometimes, other learners do too so you can help each other out!
|
||||||
|
|
||||||
|
Got all that? Great! To get started, run `rustlings watch` in order to get the first
|
||||||
|
exercise. Make sure to have your editor open!

### Collections
|
||||||
|
|
||||||
|
Rust’s standard library includes a number of very useful data
|
||||||
|
structures called collections. Most other data types represent one
|
||||||
|
specific value, but collections can contain multiple values. Unlike
|
||||||
|
the built-in array and tuple types, the data these collections point
|
||||||
|
to is stored on the heap, which means the amount of data does not need
|
||||||
|
to be known at compile time and can grow or shrink as the program
|
||||||
|
runs.
|
||||||
|
|
||||||
|
This exercise will get you familiar with two fundamental data
|
||||||
|
structures that are used very often in Rust programs:
|
||||||
|
|
||||||
|
* A *vector* allows you to store a variable number of values next to
|
||||||
|
each other.
|
||||||
|
* A *hash map* allows you to associate a value with a particular key.
|
||||||
|
You may also know this by the names *map* in C++, *dictionary* in
|
||||||
|
Python or an *associative array* in other languages.

# Error handling
|
For this exercise check out the sections:
|
||||||
|
|
||||||
Most errors aren’t serious enough to require the program to stop entirely.
|
|
||||||
Sometimes, when a function fails, it’s for a reason that you can easily interpret and respond to.
|
|
||||||
For example, if you try to open a file and that operation fails because the file doesn’t exist, you might want to create the file instead of terminating the process.
|
|
||||||

# Generics
|
### Generics
|
||||||
|
|
||||||
Generics is the topic of generalizing types and functionalities to broader cases.
|
In this section you'll learn about saving yourself many lines of code with generics!
|
||||||
This is extremely useful for reducing code duplication in many ways, but can call for rather involving syntax.
|
|
||||||
Namely, being generic requires taking great care to specify over which types a generic type is actually considered valid.
|
|
||||||
The simplest and most common use of generics is for type parameters.

# Hashmaps
|
|
||||||
|
|
||||||
A *hash map* allows you to associate a value with a particular key.
|
|
||||||
You may also know this by the names [*unordered map* in C++](https://en.cppreference.com/w/cpp/container/unordered_map),
|
|
||||||
[*dictionary* in Python](https://docs.python.org/3/tutorial/datastructures.html#dictionaries) or an *associative array* in other languages.
|
|
||||||
|
|
||||||
This is the other data structure that we've been talking about before, when
|
|
||||||
talking about Vecs.

# Lifetimes
|
|
||||||
|
|
||||||
Lifetimes tell the compiler how to check whether references live long
|
|
||||||
enough to be valid in any given situation. For example lifetimes say
|
|
||||||
"make sure parameter 'a' lives as long as parameter 'b' so that the return
|
|
||||||
value is valid".
|
|
||||||
|
|
||||||
They are only necessary on borrows, i.e. references,
|
|
||||||
since copied parameters or moves are owned in their scope and cannot
|
|
||||||
be referenced outside. Lifetimes mean that calling code of e.g. functions
|
|
||||||
can be checked to make sure their arguments are valid. Lifetimes are
|
|
||||||
restrictive of their callers.
|
|
||||||
|
|
||||||

# Options
|
|
||||||
|
|
||||||
Type Option represents an optional value: every Option is either Some and contains a value, or None, and does not.
|
|
||||||
Option types are very common in Rust code, as they have a number of uses:
|
|
||||||
|
|
||||||
- Initial values
|
|
||||||
- Return values for functions that are not defined over their entire input range (partial functions)
|
|
||||||
- Return value for otherwise reporting simple errors, where None is returned on error
|
|
||||||
- Optional struct fields
|
|
||||||
- Struct fields that can be loaned or "taken"
|
|
||||||
- Optional function arguments
|
|
||||||
- Nullable pointers
|
|
||||||
- Swapping things out of difficult situations
|
|
||||||
|
|
||||||
