Използването на to_ascii_uppercase опростява нещата, защото ти връща винаги един символ. Но не е правилно uppercase-ване за някои специални unicode-ски букви :). Разгледай (примерно) моето решение, за да видиш как можеше да се справиш, използвайки to_uppercase.

to_be_uppercased = false;

} else {

camelcased.push(char);

}

}

camelcased.replace("_", "")

}

pub fn titlecase(&self) -> String {

let mut titlecased = self.camelcase();

let first = titlecased.remove(0);

titlecased.insert(0, first.to_ascii_uppercase());

titlecased

}

pub fn kebabcase(&self) -> String {

self.word.replace("_", "-")

}

pub fn underscore(&self) -> String {

self.word.to_lowercase()

}

pub fn screaming_snakecase(&self) -> String {

self.word.to_uppercase()
