...It's similar to Russ where it's like, it's actually the same thing, right?
Because when you have a match case to a certain extent, you have to handle everything, right?
Yeah, Russ kind of forces you to look the programming in the eyes and say, no, you...
...It's just, flatly better tech for
most applications, even if you didn't have the memory safety aspect, if you
look at like enums pattern matching traits, like all the procedurally macro
driven libraries that are in there. And there's a lot of stuff like
that just made...
...I believe
there are
some where
you can
customize
the block
level,
but it's
not really
the way
Jinja 2
and Django
work,
so I try
to match
as much
as possible
that behavior.
And so
earlier you
were talking
about the
filters,
and you
were saying
how it...
...So, uh, it's basically like a huge match block, which matches for the keys and whatever.
happens.
I just, um, assign the actions and so on.
Uh, but if you want to reuse that, like, you know, use it like, um, out of the box, there
are libraries for...
...We only met in person once, but he ran the first podcast about Rust that I was aware of, New Rustation. His podcast was so polished, so well produced, so well researched. To this day, it sets the bar I'd like to match...
...Because it turns out, and I did not know this before this, that you can search for function signatures that match a given pattern using Rust-Doc now.
So you can search for things like option and then, you know, dash open angle brackets, like an arrow, and then square...
...So the idea here is that if you have an option T, then you want a method that returns true only if the value is some, the option is some, and the value inside the option matches some condition.
That's when you would use this function.
And so it...
...It's going to pick its own boundaries
that are not necessarily going to
match what you want, and then it's
going to rebuild more than you want.
Like, it's surprising.
You change the call site
and it rebuilds libtokio.
But if you do it yourself, by design...
...Um, and the reason we chose that was because it sort of matches what Noria does in a very
abstract sense of it uses flow as in water flow or in Noria's case data flow to process
things into higher fidelity data, right?
So a mill produces flour from...
...So things like break,
things like switch statement
that could be made into cases in a match.
Like these are things that we want to transform
into reasonable Rust code when possible.
It's not always possible.
C lets you do arbitrary,
bad things.
If anyone's curious of the...
...In my scripting language, I ended
up having to just have one big match
statement that was like all the
text keys that you could use and
it mapped them to async functions.
But I guess the alternative might
be modifying the library to take a
boxed closure instead, like...
...Yeah, the exhaustive pattern matching, right? But that's kind of a really a big benefit,
right? Because then it forces you to really think about what things may go wrong and then you end up
having a system which nearly never goes down. Now, what about that as an...
...you can say look at this pattern over here is this pattern match over there and we've been doing that for the stable kernels for decades again we've fallen all the bug fixes that we didn't forget that we forgot to...
...And if the client has more, it's going to keep trying to upload shell history until the count on the server matches.
And the other way around works, too.
So, if the server has more, it will keep downloading until the counts match.
I never thought it would work...
...v Matthias>It's always a good sign if other languages copy our ideas as well. For example, result types and pattern matching are commonplace now. But of course we still face challenges. Compile times for large projects remain a constant pain point. Many...
...It was all mix and match. But yeah, it's the standardization of the
IBM PC, which many people lamented at the time. I remember in the 1990s, people would rage about
the beige boxes that had invaded because they fondly remembered the Amigas of five to 10 years
earlier...
...So it's not so much,
we're just mismatching technologies, right? So we really need to find, we need to stick with something
that matches really well. So as Fermion got started, we switched our scheduler to Nomad. Still to this day,
we're running Nomad. We can schedule...
...So you have to match that. Plus you have to hit content and you have to hit content that, uh,
excites their board who may not know necessarily what exactly you're talking about. So it's a,
it's a complicated process, but it's, and it's a...
...That core then is where a lot of the optimizations take place, high-level optimizations, like pattern match, compilation, things of that nature.
And then that gets converted to kind of like a kernel inside Erlang.
But it's like a lower-level format that's just more of like...
...Those will match.
And then.
In your code, like the tooling around it.
I think JS bind gen does this as well.
And as those FB bind gen, you just say like, I'm going to return this struct.
You put a macro on it and then it gets rewritten...
"\[..\] if a breaking change is going to happen, it’s much better to make lock automatically panic than to make panics silently unlock."
