does its size vary??

MMaxine what encoding is a rust string??

AquaOP•10/7/23, 10:32 PM

apparently?? i don't know

AAqua `string[1]`

Lyris the Kitori•10/7/23, 10:32 PM

what does that mean?

AquaOP•10/7/23, 10:32 PM

char c = mystring[1]char c = mystring[1]
c == 's'c == 's'

Lyris the Kitori•10/7/23, 10:32 PM

so you want codepoints?

Lyris the Kitori•10/7/23, 10:32 PM

or characters

AquaOP•10/7/23, 10:32 PM

characters

Lyris the Kitori•10/7/23, 10:32 PM

that isnt a hard fast definition in unicode

Lyris the Kitori•10/7/23, 10:33 PM

also how big is said charchar type? itd have to be at least 21 bits long to fit all codepoints

AquaOP•10/7/23, 10:33 PM

i don't remember its size in rust

Lyris the Kitori•10/7/23, 10:34 PM

in rust, chars are unicode scalar value, and are 4 bytes in size

Lyris the Kitori•10/7/23, 10:34 PM

according to the docs

Lyris the Kitori•10/7/23, 10:34 PM

https://doc.rust-lang.org/std/primitive.char.html

char - Rust

A character type.

AquaOP•10/7/23, 10:34 PM

all i know is that to get a list of characters you can index through you gotta do:

let text: Vec<String> = "hello".to_string().chars().collect();

let text: Vec<String> = "hello".to_string().chars().collect();

which yes
does an entire damn allocation
cause charschars returns an iterator

AquaOP•10/7/23, 10:34 PM

which is fine for a lot of cases

AquaOP•10/7/23, 10:34 PM

but not when you want to jump around the string

AquaOP•10/7/23, 10:34 PM

as i need to do

Maxine•10/7/23, 10:34 PM

is there not a code_point_at

AquaOP•10/7/23, 10:34 PM

Maxine•10/7/23, 10:35 PM

can't you add that as like a trait or whatever

AquaOP•10/7/23, 10:35 PM

you can convert it to bytes

AquaOP•10/7/23, 10:35 PM

but that means youre limited to strict utf-8 only

Lyris the Kitori•10/7/23, 10:35 PM

good

Lyris the Kitori•10/7/23, 10:35 PM

use utf-8 only

Lyris the Kitori•10/7/23, 10:35 PM

dont mix

AquaOP•10/7/23, 10:35 PM

~~i need japanese charatcers~~

LLyris the Kitori use utf-8 only

Maxine•10/7/23, 10:35 PM

watch me

Lyris the Kitori•10/7/23, 10:35 PM

yes and?

Lyris the Kitori•10/7/23, 10:35 PM

utf-8 supports all unicode values? thats its whole point

AquaOP•10/7/23, 10:35 PM

nono as in

Lyris the Kitori•10/7/23, 10:35 PM

do you mean "strict ascii"?

AquaOP•10/7/23, 10:35 PM

it converts it to 1 byte per character

AquaOP•10/7/23, 10:35 PM

yes

TechPizza•10/7/23, 10:36 PM

you're not meant to index strings slugsweateyes

Lyris the Kitori•10/7/23, 10:36 PM

AquaOP•10/7/23, 10:36 PM

and then whatever the fuck the last 127 numbers of ascii are called

AquaOP•10/7/23, 10:36 PM

which is apparently not utf-8 because why would be it

AAqua and then whatever the fuck the last 127 numbers of ascii are called

Maxine•10/7/23, 10:36 PM

theyre called nothing

Maxine•10/7/23, 10:36 PM

because they dont exist

Lyris the Kitori•10/7/23, 10:36 PM

you shouldnt index strings since that doesnt really makes sense and could mean 8 million things

Perksey•10/7/23, 10:36 PM

ASCII is 7-bit

Lyris the Kitori•10/7/23, 10:36 PM

iterate over codepoints or unicode scalar values

Maxine•10/7/23, 10:36 PM

ASCII is 7-bit clean, it doesn't specify what goes in the other bit, or if one exists

Perksey•10/7/23, 10:37 PM

which is probably why it was so easy to model UTF-8 on a napkin

Perksey•10/7/23, 10:37 PM

which is actually how it was invented

Maxine•10/7/23, 10:37 PM

better than the best thing i've done on a napkin

TechPizza•10/7/23, 10:37 PM

apparently "str".chars().nth(1) works when

LLyris the Kitori you shouldnt index strings since that doesnt *really* makes sense and could mean...

AquaOP•10/7/23, 10:37 PM

all i wanna do is go if string[1] == 'c'if string[1] == 'c' like
why is this so hard

TTechPizza apparently "str".chars().nth(1) works <:when:968512924698169415>

AquaOP•10/7/23, 10:37 PM

it does yes

AquaOP•10/7/23, 10:37 PM

but that also iterates through the entire damn string

`string[1]`
