...crates it's useful like as evidenced by it's used all the cases that broke were match expression were match things whereas the inner use of interactions inside of a match block is that right looks like it looks like it yeah one of which is the dark comment...
...match on both a to Pi and B tie and just have like an exhaustive list of all the different kinds of questions that we could support um it's just that like kind of think of these as as think of these two matches as like one match just...
...take that whatever gets returned from here we're gonna match this has to be a 2-tuple we're gonna match to the first part and then and then we're gonna take the we're going to match to the first part and we'll take that Q...
...the specification is not executable, so it cannot be tested to ensure that it matches the intent of their authors, and the specification is hard to interpret, resulting in ambiguity and conflicting interpretations. Since unsafe Rust programs can suffer from UB, all of these problems also affect us in Rust...
...it it just seemed so annoying that i also probably depends where you're what you're matching against if it's something like a string and you're trying to match a string literal you're never getting exhausted this anyway i mean if let also like you know...
...to match on that yeah you want to be able correct you want to be able to use foo as the pattern in a match arm and so once you decide to do that like once you decide that you can say katsu option of some non structural match type...
...path then we can't use anything eagerly so we just jump into the check expert kind which is the big humongous match that we use to match on all the different type kinds or expert kinds in here type check um and depending on what the expert kind is...
...to restrict the use of constants in match patterns to constants where sort of they implement partial eq and eq and they implement them in a way that matches structural equality because we weren't quite sure what semantics we wanted for match so i'm not actually sure what...
...a bunch of code that is using workarounds I um fixed some bugs and pattern matching before if you tried to pattern match on a vector sometimes we took the wrong branch of the match which is really not appreciated and I'm happy that and I hope that like...
...we don't we add fake reads for everything that gets matched right uh yes whether or not we also capture it in some other way yes i think yes so if we for example move something and match it then i think we'll see a problem because the...

...write test modules and documentation tests mock out complex dependencies for simpler / more deterministic unit tests perform powerful matching on generated outputs This talk is suitable for both novice and experienced Rust developers, as well as non-Rust developers who are interested in learning more about the language.
...first it's going to be nice that if everybody X how still a match the blocks so all the matches should at the end if there is no other cases use the exhaustive match so do you see the none in there that should be underscore in most of...
...I fell in love with Rust for its cool design ideas and open governance, then started contributing in 2019 to scratch an itch and ended up the de-facto expert on pattern-matching. Since then I've been dabbling in lang design, opsem, spec and more recently type system work...
...uh then down here is the like you know we have underscore which you know if you're doing a match statement this is this is going to match all of the values like so if if it's outside of this range it's always going to come down...
...retrieval based on it so pattern matching is a very regimented approach to evaluating paths of execution and expected and unexpected outputs in rusts I'm sure a lot of you already know this pattern matching is enforced with the match keyword the match keyword is extremely useful because it...
...compiler generates something like the basic block on the right which sort of says I already knew that I matched one of all the other candidates are dead if I matched a for the first field so I don't need to generate different basic blocks so it's sort...
...use a create article error that's three buttons and this allows us instead of doing string matching as we were doing just a few moments ago to actually go and match the specific variant this is a variety of advantages uh if that pattern disappears the code is gonna...
...just like grep we find the lines that match all the words you type as you can see if I type all the things every result contains all three words yeah just like it should now if you want to match the whole phrase you just put quotes around it...
...and so there's actually runs take a rest yeah but the thing with macro rules is items that match in patterns so you've got rules here to match certain patterns your capture has whole items and so can they cannot be broken down within the macro body what...
