How to get First Character in String in Rust - Step by Step Examples

How to get First Character in String in Rust ?

In Rust, you can use array-like indexing or the chars() method to get the first character of a string.

In this example,

We create a string slice named str with a value of "Hello World".
We then access the first character using array-like indexing with index 0 on the string str or the chars() method and nth(0) to get the first character.
Finally, we print the first character.

fn main() {
    let str = "Hello World";
    let first_char = str.chars().nth(0).unwrap();
    println!("First character: {}", first_char);
}

First character: H

In this example,

We create a string slice named str with a value of "apple".
We then access the first character using array-like indexing with index 0 on the string str or the chars() method and nth(0) to get the first character.
Finally, we print the first character.

fn main() {
    let str = "apple";
    let first_char = str.chars().nth(0).unwrap();
    println!("First character: {}", first_char);
}
