What is string.chars() in Rust?
okwudili onyejiaku
Overview
The chars() method of a string in Ruby returns an iterator of characters which make up a string. The iterator returned allows us to loop through each character of the string. For instance, we can print each character with this iterator.
Syntax
The syntax for the chars() method is as follows:
ourString.chars()
Syntax for chars() method in Rust
Parameters
ourString: This is the string of which we want to get the characters as an iterator.
Return value
The value returned is an iterator.
Example
fn main() {
// create some strings
let str1 = "Rust";
let str2 = "Educative is the online learning platform!";
// print the characters in each iterator
println!("The characters in {} are:", str1);
for character in str1.chars() {
println!("{}", character);
}
println!("The characters in {} are:", str2);
for character in str2.chars() {
println!("{}", character);
}
}Get the characters in a string using the chars() method in Rust
Explanation
- Lines 3 and 4: We create some strings.
- Lines 9 and 13: We use the
chars()method to get an iterator of all the characters that make up the strings we created. Then we use thefor inloop to print each character of the iterator.
