Required Methods

fn view(&self) -> StringView<'_>

fn view_part(&self, start_idx: usize, end_idx: usize) -> StringView<'_>

fn char_idx(&self, ch: Char<'_>) -> (usize, usize)

Byte index of this Char start & end inside base str.

use string_view::StrExt;

let text = "Hello World";
let mut chars = text.chars_in_place();

let first_char = chars.next().unwrap();
assert_eq!(first_char.as_str(), "H");
assert_eq!(text.char_idx(first_char), (0, 1));

let second_char = chars.next().unwrap();
assert_eq!(second_char.as_str(), "e");
assert_eq!(text.char_idx(second_char), (1, 2));

fn chars_in_place(&self) -> CharsInPlace<'_>

fn chars_in_place_mut(&mut self) -> CharsInPlaceMut<'_>

fn make_lowercase(&mut self)

Makes str characters lowercase in-place where appropriate

fn make_uppercase(&mut self)

Makes str characters uppercase in-place where appropriate

impl StrExt for str

fn char_idx(&self, ch: Char<'_>) -> (usize, usize)

Byte index of this Char start & end inside base str.

use string_view::StrExt;

let text = "Hello World";
let mut chars = text.chars_in_place();

let first_char = chars.next().unwrap();
assert_eq!(first_char.as_str(), "H");
assert_eq!(text.char_idx(first_char), (0, 1));

let second_char = chars.next().unwrap();
assert_eq!(second_char.as_str(), "e");

fn make_lowercase(&mut self)

Makes str characters lowercase in-place where appropriate

use string_view::StrExt;

let text: &mut str = &mut String::from("HELLO World");
text.make_lowercase();
assert_eq!(text, "hello world");
 
let text: &mut str = &mut String::from("ПРИВЕТ Мир");

fn make_uppercase(&mut self)

Makes str characters uppercase in-place where appropriate

use string_view::StrExt;
