wasn't that far down

This isn't developer. Please use #showroom

oh no now i have to retrain my muscle memory to enter developer channel without seeing any tower clips

You might consider adding a key other than the spacebar in the new version to open the page of the editor's game layer. -Like Alt.

@Jupstar ✪ since c++ puts the struct,class fields in the order u define them, u think reordering the fields, can achieve better pef?

15:20

perf

Yes

rust automatically uses the best layout to have less padding and alignment

But smith different

15:20

Smth

i think we dont put thought in ddnet

15:20

when putting fields

15:20

xd

If compiler can reorder it then it can also make it more cache friendly

i think biggest to smallest

15:21

is the easy way

Ryozuki

rust automatically uses the best layout to have less padding and alignment

Less padding alignment is not always best tho

15:21

Sometimes the opposite is true actually

well less padding idk

15:22

i think it chooses the best layout

15:22

idk if it has less padding xd

When it knows stuff is accessed concurrently it can create so much alignment that no cache flushes are needed

15:23

GPUs always have insane alignments xd

The only data layout guarantees made by this representation are those required for soundness. They are:

    The fields are properly aligned.
    The fields do not overlap.
    The alignment of the type is at least the maximum alignment of its fields.

Formally, the first guarantee means that the offset of any field is divisible by that field's alignment. The second guarantee means that the fields can be ordered such that the offset plus the size of any field is less than or equal to the offset of the next field in the ordering. The ordering does not have to be the same as the order in which the fields are specified in the declaration of the type.

Be aware that the second guarantee does not imply that the fields have distinct addresses: zero-sized types may have the same address as other fields in the same struct.

There are no other guarantees of data layout made by this representation.

15:23

these are the only guarantees

15:23

in rust

Yes it was a really good idea from rust to design it like this

You can use clang-reorder-fields

And static linking

Ryozuki

i think it chooses the best layout

Mh, idk if one can rigorously define an "optimal" layout. A lot of bizarre alignment considerations, cache considerations must be made. The nature of the access is also probably important

well i guess

15:25

rust doesnt define it as the most optimal, it just says these are the guarantees

But still per architecture it can assume certain stuff

aka u must not rely on the order u define them

15:25

unlike c

Arch=native for enjoyers

based

You can benchmark to see if it's optimal, but I don't think you can just by knowing the architecture guess the best layout unless you are like the designer of the cpu

15:28

Does rust allow iteration of struct fields btw? I don't remember

wdym by that

15:30

like python dict?

15:30

xd

15:30

__dict__

15:30

@Learath2 u can do this at compile time with macros

15:30

ast macros ez

15:31

since macros operato on ast, u can know whats a struct field

Ryozuki

like python dict?

Yeah, or js ones

serde is so powerful and fast cuz that

15:31

proc macros*

Ryozuki

since macros operato on ast, u can know whats a struct field

So you just generate an iterator that yields them in order?

idk what serde does

15:32

but they need to do what u want to serialize fieldss

15:32

iirc

15:34

i am always amazed by how powerful serde is

15:34

and its perfomant af

15:34

its crazy

15:34

one of rust biggest achievements

15:35

#rustad

Learath2

Yeah, or js ones

js sux tho

15:36

if u dont use a Map

15:36

the iterator over objects may give u unwanted stuff

15:38

https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map#objects_vs._maps

Map - JavaScript | MDN

The Map object holds key-value pairs and remembers the original insertion order of the keys. Any value (both objects and primitive values) may be used as either a key or a value.

15:38

An Object has a prototype, so it contains default keys that could collide with your own keys if you're not careful.

15:38

most ppl in js world use object instead of maps

rip influxdb crate

cuz they dont even know what a map is lmao

@Learath2 no, but you can annotate the struct with a macro that can read the struct fields and generate methods based on that

Should we just move this channel, including bugs into it's own category? The channel being so far down is extremely odd to me

omg

15:41

so it wasnt u who moved it

15:41

do it

15:41

and put it on top

15:41

top priority

this reminds me i did this

a abandoned project

15:41

use formy::Form;

#[derive(Form)]
struct UserLogin {
    #[input(pattern = r"[\w]+")]
    #[label = "Username:"]
    username: String,

    password: String,
    some_field: String,
}

let form = UserLogin::to_form();

i make a html form with this macro

Sounds good then I can minimize the useless channels xd

Jupstar's point is good, I guess. I also like people stumbling upon the developer channel though, I'd guess this would reduce the chance of that happening

Jupstar's point is good, I guess. I also like people stumbling upon the developer channel though, I'd guess this would reduce the chance of that happening

ye thats a point i made

16:18

thats why it being 2nd is good

16:18

we need more devs

16:18

and im sure its interesting for ppl to look at

16:18

event if they dont comment

16:18

im pretty sure

16:18

dev channels in games are the most interesting

You can use clang-reorder-fields

im afraid this break some mem_copy between different struct. They do have similar layout, but can it guarentee it reorders similarly?

apparently it does nothing automatically

you have to specify the order you want, so not that useful

anyone knowing how to compile a modded client with 0.6 on it ?

what client?

21:33

I can guess which client you are talking about only by checking our mutual friend

yes i know, just read the README file

cheat clients rarely have instructions on the build process

nouaa

Nice (edited)

That's why I'm asking here, maybe someone knows how to do it
