rustHow to join iterator of string in Rust

Joining an iterator of strings in Rust can be done using the join method of the std::iter::Iterator trait. This method takes a single argument, which is the separator string to be used between each string in the iterator. The following ## Code example shows how to join an iterator of strings using the join method:

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

println!("{}", joined_string);

Output

Hello, World, !

Explanation:

• let strings = vec!["Hello", "World", "!"];: This line creates a vector of strings containing the elements "Hello", "World" and "!".
• let joined_string = strings.iter().join(", ");: This line uses the join method of the std::iter::Iterator trait to join the strings in the vector with the separator string ", ".
• println!("{}", joined_string);: This line prints the joined string to the console.
