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 newStringobject with the valueHello World!.let substring = s.get(0..5).unwrap();: This line calls the.get()method on theStringobjectswith the parameters0and5. This will return aSomeobject containing the substringHello. The.unwrap()method is used to extract the value from theSomeobject.
