rustrust string as char array

A Rust String can be converted to a char array using the .chars() method. This method returns an iterator over the characters of the string.

Example code

let my_string = "Hello World!";
let char_array: Vec<char> = my_string.chars().collect();

Output example

[ 'H', 'e', 'l', 'l', 'o', ' ', 'W', 'o', 'r', 'l', 'd', '!' ]

Code explanation

• let my_string = "Hello World!";: This line declares a String variable called my_string and assigns it the value "Hello World!".
• let char_array: Vec<char> = my_string.chars().collect();: This line declares a Vec<char> variable called char_array and assigns it the result of the .chars() method called on my_string. The .chars() method returns an iterator over the characters of the string, and the .collect() method collects the iterator into a Vec<char>.
