Hi, im trying to complete the task above but I'm getting error[E0463]. I see that I may need to add the crate as one of the dependencies but i'm unsure as to how to do that... Could someone please help me? Thx in advance

Could you share your code, the test code and test failure? Please use codeblocks. Please do not use screenshots.

||extern crate unicode_segmentation;
use unicode_segmentation::UnicodeSegmentation;
pub fn reverse(input: &str) -> String {
todo!("Write a function to reverse {input}");
let input = input.to_string();
let output: String = x.graphemes(true).rev().collect();
}||
Is this ok?

The unicode_segmentation crate is only used if you enable the optional grapheme feature. The command to run the tests with this feature is in the exercise's instructions:
cargo test --features grapheme
dry ether
The crate still won't be automatically added - edit Cargo.toml to add it as a dependency https://doc.rust-lang.org/cargo/reference/specifying-dependencies.html
