Struct mut_str::Char

pub struct Char { /* private fields */ }

A UTF-8 encoded character.

This type can only be obtained as a reference or mutable reference similarly to str.

use mut_str::Char;

let s = "Hello, World!";
let c = Char::get(s, 1).unwrap();

assert_eq!(c, 'e');

Implementations

impl Char

pub const unsafe fn new_unchecked(p: *const u8) -> *const Self

Create a new character reference from a pointer to a character.

Safety

p must be a pointer to the first byte of a valid UTF-8 character.

pub const unsafe fn new_unchecked_mut(p: *mut u8) -> *mut Self

Create a new mutable character reference from a mutable pointer to a character.

Safety

p must be a mutable pointer to the first byte of a valid UTF-8 character that can be mutated. String literals cannot be mutated.

pub fn get(s: &str, i: usize) -> Option<&Self>

Get a character reference from a str and an index.

use mut_str::Char;

let s = "Hello, World!";
let c = Char::get(s, 1).unwrap();

assert_eq!(c, 'e');

pub fn get_mut(s: &mut str, i: usize) -> Option<&mut Self>

Get a mutable character reference from a mutable str and an index.

use mut_str::Char;

let mut s = Box::<str>::from("Hello, World!");
let c = Char::get_mut(&mut *s, 1).unwrap();

assert_eq!(c, 'e');

pub fn len(&self) -> usize

Get the length of the character in bytes.

This will be in the range 1..=4.

use mut_str::Char;

let s = "oΦ⏣🌑";

assert_eq!(Char::get(s, 0).unwrap().len(), 1);
assert_eq!(Char::get(s, 1).unwrap().len(), 2);
assert_eq!(Char::get(s, 2).unwrap().len(), 3);
assert_eq!(Char::get(s, 3).unwrap().len(), 4);
