How to Check if String contains specific Character in Rust ?

Answer

To check if a string contains a specific character in Rust, you can use the 'contains' method of the string type.

✐ Examples

1 Check if String contains specific Character using 'contains' method

In this example,

We create a function 'contains_character' that takes a string and a character as input.
We use the 'contains' method of the string to check if the character is present in the string.
If the character is found, 'true' is returned; otherwise, 'false'.
Finally, we print the result.

Rust Program

fn contains_character(s: &str, ch: char) -> bool {
    s.contains(ch)
}

fn main() {
    let s = "Hello World";
    let ch = 'W';
    let contains = contains_character(&s, ch);
    println!("String contains character '{}': {}", ch, contains);
}

Output

String contains character 'W': true
