Slicing a String

What Is Slicing?

  • Slicing is used to get a portion of a string value.

  • Syntax The general syntax is:

  let slice = &string[start_index..end_index]

Here,

  • start_index and end_index are the positions of starting and ending index of the original array respectively.

    • Note: The start_index is inclusive and end index is exclusive

  • & indicates that the variable slice borrows the string.

    • Note: The minimum value of start_index is 0 and the maximum value is the size of the string
     fn main() {
   let string = "Rust Programming".to_string();
   let slice = &string[5..12]; 
   // get characters at 5,6,7,8,9,10 and 11 indexes
   println!("Slice : {}", slice);
}

output

  Slice : Program
