How to Check if String contains only Alphabets in Rust - Step by Step Examples
How to Check if String contains only Alphabets in Rust ?
Answer
To check if a string contains only alphabets in Rust, you can iterate through each character and check if it is an alphabet using functions like char::is_alphabetic
.
✐ Examples
1 Check if String contains only Alphabets using loop to check each character
In this example,
- We create a string named
str
with a value of"Hello123"
. - We iterate through each character in the string and check if it is an alphabet using the
is_alphabetic
method of thechar
type. - If all characters are alphabets, we set
contains_only_alphabets
totrue
, otherwisefalse
. - Finally, we print the result to the console.
Rust Program
fn main() {
let str = String::from("Hello123");
let mut contains_only_alphabets = true;
for c in str.chars() {
if !c.is_alphabetic() {
contains_only_alphabets = false;
break;
}
}
println!("String contains only alphabets: {}", contains_only_alphabets);
}
Output
String contains only alphabets: false

In this tutorial, we learned How to Check if String contains only Alphabets in Rust language with well detailed examples.
