How to create a slice from a string in Rust?

// plain

Creating a slice from a string in Rust is a simple process. The &str type is a slice that points to a specific point in a String type. To create a &str from a String, you can use the as_str() method.

let my_string = String::from("Hello World!");
let my_slice = my_string.as_str();
println!("{}", my_slice);

Output example

Hello World!

The code above creates a String type called my_string and then creates a &str type called my_slice from my_string using the as_str() method. Finally, the println! macro is used to print the contents of my_slice.

Code explanation

• let my_string = String::from("Hello World!");: creates a String type called my_string
• let my_slice = my_string.as_str();: creates a &str type called my_slice from my_string using the as_str() method
• println!("{}", my_slice);: prints the contents of my_slice using the println! macro
