rustHow do I get a substring from a string in Rust?
You can get a substring from a string in Rust using the .get()
method. This method takes two parameters, the starting index and the length of the substring.
Example code
let s = String::from("Hello World!");
let substring = s.get(0..5).unwrap();
Output example
Hello
Code explanation
let s = String::from("Hello World!");
: This line creates a newString
object with the valueHello World!
.let substring = s.get(0..5).unwrap();
: This line calls the.get()
method on theString
objects
with the parameters0
and5
. This will return aSome
object containing the substringHello
. The.unwrap()
method is used to extract the value from theSome
object.
