I'm [? Raif ?] Levine of the Android UI Toolkit Team.

And it is my pleasure to introduce today Alex Crichton

And he is a member of the Rust core team.

one of the more exciting and interesting languages,

So I'm going to give just a whirlwind tour of what Rust

get if I ever talk about a programming language is

So if you take a look around, we have this whole landscape

of programming languages today, they all fill various niches.

But it turns out that you can organize these languages

So on one end of the spectrum, we have C and C++,

We know exactly what's going to run our machine.

We have lots of control over memory layout.

We have segfaults, buffer overruns, very common bugs

Whereas on the other side, we have JavaScript.

They're very safe languages, but you don't quite

So in JavaScript, we have JITs behind the scenes,

or you really don't know what's going to happen.

Because it'll change as the program is running.

Rust is saying, we are not going to give you

But rather, we're going to give you both.

So Rust is a systems programming language which is kind

of filling this niche that hasn't been filled by many

of the languages today, where you get both the very low-level

control of C and C++, along with the high-level safety

and constructs that you would expect from Ruby,

What kind of niches will benefit from this safety

to write a parallel layout engine in Rust.

And it benefits from this control, this very high level

Because browsers are very competitive in performance,

But at the same time, all major browsers today are written

in C++, so they're not getting this great level of safety.

They have a lot of segfaults, memory vulnerabilities.

But by writing in Rust, we're able to totally eliminate

if you try and retrofit parallelism onto, for example,

Gecko, which is millions of lines of C++,

So by using a language which from the ground up

we're able to do very ambitious things like paralyzing layout.

It's a product of Tilde, where what they did

is they have a component that runs inside of the customer's

Rails apps will just kind if monitor how long it takes

to talk to the database, how long it takes for the HTTP

request, general analytics and monitoring about that.

But the key aspect here is that they have very tight resource

They're a component running in their client's application.

and they decided to rewrite their gem in Rust.

And Rust is great for this use case because with the low level

of control that you get in C+, C, and C++,

they were able to satisfy these very tight memory constraints,

But also, they were able to not compromise the safety

So this is an example where they would have written their gem
