Module rune::alloc::string

source ·
Expand description

A UTF-8–encoded, growable string.

This module contains the String type, the TryToString trait for converting to strings, and several error types that may result from working with Strings.

§Examples

There are multiple ways to create a new String from a string literal:

use rune::alloc::String;
use rune::alloc::prelude::*;

let s = "Hello".try_to_string()?;

let s = String::try_from("world")?;
let s: String = "also this".try_into()?;

If you have a vector of valid UTF-8 bytes, you can make a String out of it. You can do the reverse too.

use rune::alloc::{try_vec, String};
use rune::alloc::prelude::*;

let sparkle_heart = try_vec![240, 159, 146, 150];
let sparkle_heart = String::from_utf8(sparkle_heart)?;

assert_eq!("💖", sparkle_heart);

let bytes = sparkle_heart.into_bytes();

assert_eq!(bytes, [240, 159, 146, 150]);
