Expand description

An owned latin-1 encoded string

Implementations§

Source§

impl Latin1String

Source

pub const unsafe fn new(inner: Box<[u8]>) -> Self

Create a new string

§Safety

Must not contain null bytes

Source

pub fn encode(string: &str) -> Cow<'_, Latin1Str>

Create a new instance from a rust string.

Note: This encodes any unavailable unicode codepoints as their equivalent HTML-Entity. This is an implementation detail of the encoding_rs crate and not really useful for this crate.

use latin1str::Latin1String;

assert_eq!(Latin1String::encode("Hello World!").as_bytes(), b"Hello World!");
assert_eq!(Latin1String::encode("Frühling").as_bytes(), b"Fr\xFChling");
Source

pub fn read_cstring<R: BufRead>(reader: &mut R) -> Result<Self, Error>

Create a new instance by reading from a BufRead until a null terminator is found or the end of the string is reached.

use std::io::{Read, Cursor};
use latin1str::Latin1String;

let bytes = b"Hello World!\0";
let mut cur = Cursor::new(bytes);
let s = Latin1String::read_cstring(&mut cur).unwrap();
assert_eq!(s.decode().as_ref(), "Hello World!");
assert_eq!(cur.read(&mut []).ok(), Some(0));

Methods from Deref<Target = Latin1Str>§

Source

pub fn as_bytes(&self) -> &[u8]

Get the bytes of the string

let s = Latin1Str::from_bytes_until_nul(b"Hello World!");
assert_eq!(s.as_bytes(), b"Hello World!")
Source

pub fn len(&self) -> usize

Get the bytes of the string

Source

pub fn is_empty(&self) -> bool

Check whether the str is empty

assert!(Latin1Str::from_bytes_until_nul(b"").is_empty());
assert!(!Latin1Str::from_bytes_until_nul(b"a").is_empty());
Source

pub fn decode(&self) -> Cow<'_, str>

Decode the string

let s = Latin1Str::from_bytes_until_nul(b"Fr\xFChling");
assert_eq!(s.decode().as_ref(), "Frühling");
