How to split a Strings in Rust example

This tutorial shows you multiple ways to split a string with a separator.

#How to Split a String with space in Rust?

There are multiple ways to do this .

• Using the split Function

  The split function within the String object separates the string based on a specified pattern and returns an iterator.

  The split method divides a string into multiple slices using spaces, separators, or characters.

  You can iterate over the result using a for loop, or you can convert it to a Vec<&str> using the collect method.

  fn main() {
      let name = "Hello John";
  
      for item in name.split(" ") {
          println!("{}", item);
      }
      let items: Vec<&str> = name.split(" ").collect();
      println!("{}", items[0]);
      println!("{}", items[1]);
  }
  

  Output:

  Hello
  John
  Hello
  John
  

• split_whitespace function function

  The split_whitespace function returns an iterator by splitting the string using whitespace as the separator.

  Here is an example program

  fn main() {
      let name = "Hello John";
  
      for item in name.split_whitespace() {
          println!("{}", item);
      }
      let items: Vec<&str> = name.split_whitespace().collect();
      println!("{}", items[0]);
      println!("{}", items[1]);
  }
