How to get a character of a string by index in Rust? String indexing

Hello everyone! I just started learning Rust and encountered a problem that confuses me a lot. I'm used to other programming languages, like Python or C++, where you can simply write `my_string[0]` and get the first character. In Rust, I tried to do the same thing, and the compiler gave me an error. Here's my code: ```rust fn main() { let hello = String::from("Привет"); let first_char = hello[0]; // Error! println!("First character: {}", first_char); } ``` The compiler says something about `the trait bound 'String: Index<{integer}>' is not satisfied`. Honestly, I don't understand why strings can't be indexed like regular arrays. After all, a string is a sequence of characters, right? I tried googling, but the answers on English Stack Overflow are too complicated for a beginner.
