rustHow to join array into string in Rust

Joining an array into a string in Rust can be done using the join method. This method takes a separator as an argument and returns a String.

Code example:

let arr = ["Hello", "World"];
let joined_string = arr.join(" ");
println!("{}", joined_string);

Output

Hello World

Explanation:

1. The let arr = ["Hello", "World"]; line creates an array of strings.
2. The let joined_string = arr.join(" "); line calls the join method on the array, passing in a space as the separator.
3. The println!("{}", joined_string); line prints the joined string to the console.
