title: Memory Management in Rust
---
The following post is based on [this](https://www.youtube.com/watch?v=ClFyJWzjZmU) talk from [RustConf](http://rustconf.com/).
The talk starts by explaining some background about memory management.
Memory management is related with two major problems:
* How do we ensure that we don't access memory that we don't own?
* How do we ensure that we don't access memory after it has been freed?
The first problem is about memory safety; we want our programs not crash when trying to access memory we don't own.
The second problem relates with memory leaks; if we forget about freeing memory after using it or if we try accessing memory after freeing it.
The traditional solution was manual memory management; when you allocate memory you are responsible for freeing it later.
A better solution was automatic garbage collection (GC); when objects are no longer referenced by anything they are automatically freed.
This solution solves both problems; no one can access objects that are not referenced anymore (they are freed). There is no need for programmers to explicitly free objects (problem #2).
However there is an important drawback; performance.
GC adds overhead because it needs some kind of runtime system (like reference counting or tracing).
Also GC pauses program execution when it runs.
Rust has a different approach; instead of automatically tracking references at runtime Rust requires programmers explicitly tell which objects are being referenced.
Rust uses ownership rules.
An object has an owner; only one owner at any time.
When the owner goes out of scope its destructor runs.
If an object has more than one reference it must be immutable (to avoid data races).
Rust compiler enforces these rules statically; at compile time.
This means there is no runtime overhead.
However there is one trade-off; programmer productivity.
It takes some time learning these rules.
Also writing correct code according these rules can be challenging.
Now let's see how ownership works in practice.
We start with variables.
In Rust every variable has ownership.
When you assign one variable into another its value gets moved (copy) into new variable.
So now new variable owns it.
When variables go out of scope its destructor gets called.
The destructors call `drop` function.
`drop` does nothing special if object implements `Drop` trait or if `drop` isn't implemented; then Rust calls destructor automatically.
So what happens when we assign one variable into another?
It doesn't copy values directly; it moves values.
That means after moving values original variable cannot be used anymore because its value doesn't exist anymore.
We can move values back again using `clone`.
That means calling `clone` will create new instance of object instead of moving existing one.
Let's see some examples:
{% highlight rust %}
let s1 = String::from("Hello");
let s2 = s1;
println!("{}, world!", s1);
{% endhighlight %}
We create string `s1` then assign it into `s2`.
This means `s1` value gets moved into `s2`.
So now only `s2` owns its value.
Trying printing `s1` causes error because its value doesn't exist anymore.
{% highlight rust %}
let s1 = String::from("Hello");
let s2 = s1.clone();
println!("{}, world!", s1);
{% endhighlight %}
Now we use `clone` instead so now both `s1` and `s2` have same value.
Another example:
{% highlight rust %}
fn main() {
let x = vec![1,2,3];
let y = x;
println!("x[0] is {}", x[0]);
}
{% endhighlight %}
Here we create vector `x` then assign it into `y`.
That means `x[0]` causes error because its value doesn't exist anymore.
What if we return values from functions?
If function returns something it moves its value into return value.
Let's see example:
{% highlight rust %}
fn main() {
let v = vec![1,2];
let v = takes_and_gives_back(v);
println!("v[0] is {}", v[0]);
}
fn takes_and_gives_back(a_vec: Vec) -> Vec{
a_vec
}
{% endhighlight %}
Here function takes vector as argument then returns same vector back.
Since function returns vector it moves its value into return value.
So now only return value owns vector so trying accessing vector via argument causes error!
But what if we want returning function also own returned object?
We can use mutable references:
{% highlight rust %}
fn main() {
let mut v = vec![1,2];
v = takes_and_gives_back(&mut v);
println!("v[0] is {}", v[0]);
}
fn takes_and_gives_back(a_vec: &mut Vec) -> &mut Vec{
a_vec
}
{% endhighlight %}
Here function takes mutable reference then returns same reference back.
Since function returns reference now original vector still exists so no errors!
Now let's see examples with structs:
{% highlight rust %}
struct User {
name: String,
email: String,
active: bool,
}
fn main() {
let user1 = User {
name: String::from("John Doe"),
email: String::from("[email protected]"),
active: true,
};
let user2 = user1;
println!("user1 active? {}", user1.active);
}
{% endhighlight %}
We create struct instance then assign it into other variable.
That means only second variable owns instance so trying accessing instance via first variable causes error!
What if we want keep using first variable?
We can use `clone`.
{% highlight rust %}
struct User {
name: String,
email: String,
active: bool,
}
fn main() {
let user1 = User {
name: String::from("John Doe"),
email: String::from("[email protected]"),
active: true,
};
let user2 = user1.clone();
println!("user1 active? {}", user1.active);
}
{% endhighlight %}
Now both variables owns same instance so no errors!
Another example:
{% highlight rust %}
struct User<'a>{
name: &'a str,
email: &'a str,
active: bool,
}
fn main() {
let name = "John Doe";
let email = "[email protected]";
let user1 = User {
name,
email,
active: true,
};
let user2 = user1;
println!("user1 name? {}", user1.name);
}
{% endhighlight %}
Here struct instances uses references instead strings so now instances are not owned by variables but by original references!
Since original references still exists no errors occur!
However since instances now depends on original references lifetime must be specified!
Now let's see more complex example:
{% highlight rust %}
struct User<'a>{
name: &'a str,
email: &'a str,
active: bool,
}
impl<'a>'a User{
fn status(&self) -> String{
if self.active{
format!("{} ({}) is active", self.name,self.email)
} else{
format!("{} ({}) isn't active", self.name,self.email)
}
}
}
fn main() {
let name = "John Doe";
let email = "[email protected]";
let user1 = User {
name,
email,
active:true,
};
println!("{}",user1.status());
}
{% endhighlight %}
Here struct instance uses lifetime parameter `'a`.
Lifetime parameter specifies how long struct instance lives; until original references live!
Function inside implementation block also uses lifetime parameter `'a`.
That means function requires struct instance as argument!
This allows us avoiding passing each reference individually!
Another example:
{% highlight rust %}
struct User<'a>{
name:&'a str,
email:&'a str,
active : bool,
}
impl<'a>User<'a>{
fn status(&self) -> String{
if self.active{
format!("{} ({}) is active",self.name,self.email)
} else{
format!("{} ({}) isn't active",self.name,self.email)
}
}
}
fn main(){
let name ="John Doe";
let email ="[email protected]";
let u=user_function(name,email);
println!("{}",u.status());
}
fn user_function<'b>(name:&'b str,email:&'b str)->User<'b>{
User{
name,email,true
}
}
{% endhighlight %}
Here we pass each reference individually into function then return struct instance back.
Function also uses lifetime parameter `'b`.
This way function knows how long returned struct instance lives!
Finally let's see how ownership works with collections:
{% highlight rust %}
fn main(){
let v=vec![10,20];
print_vec(v);
print_vec(v);
}
fn print_vec(v :Vec){
for i in &v{
println!("{}",i);
}
}
{% endhighlight %}
We create vector then pass it into function twice!
No errors occur because:
* Vector doesn't move its values inside function!
* Function receives immutable reference instead!
That means original vector still exists!
However if we try passing mutable reference into function twice:
* We get error because mutable references can't coexist together!
* Function must take immutable reference instead!
In summary ownership rules are:
* Every value has owner;
* Owner determines how long
