rustHow to join list of strings in Rust

Joining a list of strings in Rust can be done using the join method of the String type. The join method takes a Vec<&str> as an argument and returns a String with the elements of the Vec joined together.

Code example:

let list_of_strings = vec!["Hello", "World"];
let joined_string = list_of_strings.join(" ");

Output

Hello World

Explanation of code parts:

1. let list_of_strings = vec!["Hello", "World"]; - This line creates a Vec of &strs containing the strings "Hello" and "World".
2. let joined_string = list_of_strings.join(" "); - This line calls the join method on the Vec of &strs, passing in a single space as the separator. This returns a String with the elements of the Vec joined together with a single space.
