It's garbage because it's filtering anything beyond basic Latin characters without a reason. For example, it makes it impossible to use the General Punctation block (U+2000–U+206F) and any code sequences which allow you to triforce.
Also while getting notified of forbidden text might be useful, what's the purpose of applying word filters client-side?

Also, this is mainly for a preview window :)

A few tips just from scanning over it:
- use &str instead of &String for most cases, the latter coerces into the former and it lets you pass string literals as well, unless you specifically want to get its allocated capacity or something
- you can trim strings using str::trim(), that'll take care of trimming leading/trailing whitespace

ty. I used String mainly because I am afraid of the lifetime hell.

So user, what color are your programming socks? Have you taken your HRT yet?

>ty. I used String mainly because I am afraid of the lifetime hell.
As a rule of thumb: Things which HAVE strings should use "String", things which USE strings should use "&str".

Also when the length of the string can be known at the compile time

for caring about "programming safety" you rustfags go out of your way to use shitty insecure gui libraries

senpai.s becomes senpaitachi
nonbreakable space and a bunch of similar characters become breakable spaces

>filter list contains "back2reddit"
>code only checks single words
You might be better off doing something like this for checking filters:
for banned_word in SCREENED_KEYWORDS {
if arg.contains(banned_word) {
#[cfg(debug_assertions)]
{
println!("Keyword matches found: {}; keyword: {}", word, keyword);
}
return false;
}
}

Optionally you could keep the word splitting but add a var specifically for "back2reddit" that keeps track of progress while matching each word in the phrase:
// "back2reddit" progress counter
let mut btr_counter = 0;

for word in arg.split_ascii_whitespace() {
if word == "back" {
btr_counter = 1;
} else if word == "to" && btr_counter == 1 {
btr_counter = 2;
} else if word == "reddit" && btr_counter == 2 {
// full phrase found in order
return false;
} else {
btr_counter = 0;
}
}

Also fuck this spam filter.

4channel sanitize can take a &str instead of &String, can't it?

References implementing Deref get dereferenced when passed to other functions. Thus &String actually becomes &str.

It can, I should've updated it to take &str now

Apart from capitalised Cuck, it Jow Forums doesn't look for keywords in the middle of the word

Learn regex, retard.

yes, which is why you declare it with &str so it can take either. If the function definition is &String then you wouldn't be able to pass it a string literal
