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 thejoin
method of thestd::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.
