Module borsh::maybestd::string 1.0.0[−][src]
A UTF-8–encoded, growable string.
This module contains the String
type, the ToString
trait for
converting to strings, and several error types that may result from
working with String
s.
Examples
There are multiple ways to create a new String
from a string literal:
let s = "Hello".to_string(); let s = String::from("world"); let s: String = "also this".into();
You can create a new String
from an existing one by concatenating with
+
:
let s = "Hello".to_string(); let message = s + " world!";
If you have a vector of valid UTF-8 bytes, you can make a String
out of
it. You can do the reverse too.
let sparkle_heart = vec![240, 159, 146, 150]; // We know these bytes are valid, so we'll use `unwrap()`. let sparkle_heart = String::from_utf8(sparkle_heart).unwrap(); assert_eq!("💖", sparkle_heart); let bytes = sparkle_heart.into_bytes(); assert_eq!(bytes, [240, 159, 146, 150]);
