rustHow to join chars to string in Rust

Joining chars to string in Rust can be done using the collect() method. The collect() method takes an iterator of type char and returns a String.

Code example:

let chars = vec!['a', 'b', 'c'];
let string: String = chars.iter().collect();

Output

string will be equal to "abc"

Explanation:

• let chars = vec!['a', 'b', 'c'];: This line creates a vector of type char containing the characters a, b, and c.
• let string: String =: This line declares a variable of type String called string.
• chars.iter(): This line creates an iterator of type char from the vector chars.
• .collect(): This line collects the iterator of type char into a String.
