...And the test harness actually checks to see whether or not standard error matches the standard error file and so forth.
And so if you want to see how that happens from end to end to improve an error message, um, this is a really useful PR to see, uh...
...how
much of my code has docs? Or how much of
my docs match my code? Or
what is my test coverage?
Not necessarily like what is my code
coverage, but like how many places did I
say: hey, I'm testing this function or
I'm testing this module...
...what we actually do is sort of speed up and slow down the clock slightly to sort of get its frequency to match the real frequency. And this is tricky because the frequency actually depends on like the temperature in the room, for instance...
...Actually, some email clients, when you have, like, a rule editor, a mail filter editor with a UI,
for example, it says if from matches up, then do this or do that.
Many mail clients, well, the only way they have is they want, if they want to implement server...
...sort of hooking into python's import mechanism
when you ask python to import a file it can look at native compiled code that matches a name it's
expecting and try and import native code from that and it will run it where python's calling you but
you...
...So kind of assert struct, which was ⁓ a development kind of like a testing tool, pattern matching, an assertion for... ⁓ complex structures, of like imagine like if you want to do really fancy match statements pass of what Rust lets you do for tests. That's what assert struct is...
...can have a bunch of if
statements and string checking and tag checking to say i only want data from this channel if it matches
greater than 90 on this data point or if this value is greater than that value and it has this tag so we
have that...
...So in Rust, you're probably having a match
statement that's exhaustive and you're
going to handle this, or you're going
to have to unwrap an option or whatever.
So Rust, I think at least
surfaces this concern.
But if you just slap a question mark
after...
...I didn't even think about mixing and matching, because like you said, I always think about them coming as some kind of cohesive pair that can never be split up, right?
And now that you mentioned this, okay, it does make sense that they would be very closely linked...
...Which are those?
I mean, I would figure that
that'd actually be at a protocol layer
because supposedly,
you know, Erlang is very good
about binary manipulation
and pattern matching, right?
Yeah.
It's interesting you brought that up.
Erlang is really good
at binary manipulation.
And I think...
...As long as you stay under one gigabyte, it matches the current Rust standard library behavior
where it's n divided by two. And if it's more than a gigabyte, it will actively try to reduce its
memory usage by switching to a strategy that uses n divided by...
...I haven't fully seen the results of that survey yet, but I, you know, I'm really interested to kind of find out what people said to that and see if they kind of match my thinking as well.
So once, you know, once we can find results from...
...Program Structure Interface. Then we take that and we build a cleaned up, type checked version of your program, that matches how Rust understands the code. And this is called typed high-level intermediate representation. And after that, MIR comes, which is...
...And also to the, we want that mental
model of how things work, to match
reality as closely as possible. If you use a variable inside a loop, it's And
then use it outside the loop, you know it's fine. And, up until, I want to say,
2018...
...Uh, also, what says also the static data type and syntax like match and others teach engineers to be accurate with dealing with data and make sure data flow in the system is on the right way.
Yes.
For example, yeah, the, the exhaustive match, uh, I really like a...
...You have to match on the discriminant of
the enum and then know if it's a string,
if it's a number, if it's whatever.
Also, it's inefficient for a bunch
of other reasons, but the reason
serde has methods per type is
that it can inline...
...Yeah, I thought that there's, I don't know, I know in JavaScript, there's a way that you can,
it's not a decompile, but when you compile it, you can compile some kind of existing file that can
kind of go side by side and match up...
...A lot of techniques that don't match up.
And now you do testing and how you do things.
So all in all, I've actually found it, like, not too different.
Obviously, the scale is completely different, but that's different about it.
Different axis.
So you mentioned before...
...videos presented by one of the other co-founders
he was talking about i think somewhat like the redraw rate on your monitor should match the
redraw rate on your editor and i think wow that's could be this could be quite tough yeah i mean are
you doing...
...I'm surprised you just don't match.
Like, we just don't have like wrappers around them.
We just don't have interfaces that abstract away from some of this.
That's just like, it's overhead for the maintainers, right?
Especially for some of these things.
Like, we...
"Now macros are fine, I mean we use them for implementing internals and you know if you have something that \[...\] needs to be implemented for lots an..."
