rustHow to create a slice from a string in Rust?
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 aString
type calledmy_string
let my_slice = my_string.as_str();
: creates a&str
type calledmy_slice
frommy_string
using theas_str()
methodprintln!("{}", my_slice);
: prints the contents ofmy_slice
using theprintln!
macro
