How to Check if String contains only Alphabets and Numbers in Rust ?

Answer

To check if a string contains only alphabets and numbers in Rust, you can use the chars iterator and the is_alphanumeric method.

✐ Examples

1 Check if String contains only Alphabets and Numbers using character iteration

In this example,

We create a function contains_only_alphabets_and_numbers that takes a string reference as input.
We iterate through each character of the string using the chars iterator.
For each character, we check if it is alphanumeric using the is_alphanumeric method.
If all characters are alphabets or numbers, we return true, otherwise false.
Finally, we print the result.

Rust Program

fn contains_only_alphabets_and_numbers(s: &str) -> bool {
    s.chars().all(|c| c.is_alphanumeric())
}

fn main() {
    let s = "Hello123";
    let result = contains_only_alphabets_and_numbers(s);
    println!("String contains only alphabets and numbers: {}", result);
}

Output

String contains only alphabets and numbers: true
