[−][src]Module bumpalo::collections::string
A UTF-8 encoded, growable string.
This module contains the String
type and several error types that may
result from working with String
s.
Examples
You can create a new String
from a string literal with String::from_str_in
:
use bumpalo::{Bump, collections::String}; let b = Bump::new(); let s = String::from_str_in("world", &b);
You can create a new String
from an existing one by concatenating with
+
:
use bumpalo::{Bump, collections::String}; 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.
use bumpalo::{Bump, collections::String}; let b = Bump::new(); let sparkle_heart = bumpalo::vec![in &b; 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]);
