...s add that's vital info to github repos um it has a content script that matches the domain github.com so we have a permission model and with the content script matching you can basically just say hey i don't need every domain i just need this domain...
...also mean you can do it at a lower level of the pattern like if you know you're matching inside of a uh a new type can you match a an or pattern inside the parens of the new type or do you need an additional set of parens...
...of the time you will little there writing code sort of like this that extracts out this sty field and matches on it and why do I say match because what this sty a field stores is something called a type kind and this is kind if you're familiar...
...on this is through this little method called Joey and what that will do is it will itinerate over all of the components that match the pattern so everything that's a position has a position and has a velocity will get returned and then we can act on them...
...and you can make a you know them that contains a huge 64 and you set it to a lion one and it'll match safely and not give you an edge so that should get fixed before we talk about the stabilization you know something in the issue okay...
...Here's the place so far, but it doesn't yet match any of my captures right it's like an incomplete match. And then when we get to the Dobie we would say, oh, I'm adding the field be Nicholas Matsakis: I'm extending this place I have...
...programming in rest feels like to me I would say it feels kind of like si would feel if it had strong typing pattern matching type inference and a lot of features that encourage modularity and higher River programming and you'll see some of what I mean by that...
...Somehow, it didn't quite there was like a pattern match that I was having. When do you how do you remember when you have to write down the names like types you do assumptions, you know, Nicholas Matsakis: It didn't doesn't match, but Nicholas Matsakis: I don...
...have the you don't have you aren't forced to do this you aren't forced to but it's more you are matching the structure ritual ously renaming the field to something else doesn't seem valuable here if you do if you when you actually put name...
...to be a crater run uh i guess the question is whether we have any results this was if we were going to change match patterns looks like we don't yet have those results okay i'm going to unnominate this and request that people nominate once we have...
...only that some type of memory safety but you know other other stuff that it's there and it's really nice like pattern matching sorry I'm a little bit so yeah that would be nice thank you very much so also it was I was not I was...
...equals expression is evaluate the expression to a place if it's not already one and then match it against the pattern and evaluating it produces the ampersand x which then gets matched against underscore which means that nothing happens to it um so it drops so it falls out...
...So that would be a little bit annoying for the clients because they would have to match over a string when they match different error messages which isn't ideal. And yeah to be honest default error handling in JavaScript is probably not the best anyways because you will have...
...Of dollar value in there are in a vector like when this thing matches when I think the actual proposal that they have something like dollar hash value. I don't know. Anyway, um, Nicholas Matsakis: But there was another couple comments but might be interesting. Nicholas Matsakis: There you...
...be by ref see by me these are the things that match up exactly to what the original type is and what the expected type is there's no interesting compatibility issue here it's just inputs match the outputs and when we run this you get exactly what you...
...you don't know rest is a memory safe multi-paradigm programming language that features our cost abstractions ownership semantics trade based generics pattern-matching static typing and syntactic macros that's that's the part I did a sort of some context a macro is a function that works...
...like to recurse so the way to deconstruct my my list is to match on it and the case i'd like to write is that some box ref tail right this is how we match on the on the tail structure this gives me uh so now i want...
...of ls pass it into this filter this where command and by saying where i actually down select or filter down to just what matches this and you can see there's a lot of inspiration for rust going on behind the scenes ls is giving me an iterator if...
...in the list and counts how many items there are as you can see we use a match expression something that i was not into anticipating teaching to students racket does have match expressions but this is something that wasn't introduced during fundies one and so there's not...
...So I guess the question is should we, it might be more convenient also in chalk sometimes to match on like there's an advantage to matching on the field just that you don't have Nicholas Matsakis: As much reference stuff going around kind of Nicholas Matsakis: If you...
