Struct UnicodeString 

pub struct UnicodeString(pub Vec<char>);

A character-indexed string stored as a vector of chars, allowing indexing and editing by Unicode scalar value rather than by byte offset.

Tuple Fields

0: Vec<char>

Implementations

impl UnicodeString

pub fn clear(&mut self)

Removes all characters, leaving the string empty.

pub fn pop(&mut self) -> Option<char>

Removes and returns the last character, or None if the string is empty.

pub fn remove(&mut self, index: usize) -> char

Removes and returns the character at the given index, shifting subsequent characters left.

pub fn len(&self) -> usize

Returns the number of characters in the string.

pub fn is_empty(&self) -> bool

Returns true if the string contains no characters.

pub fn is_not_empty(&self) -> bool

Returns true if the string contains at least one character.

pub fn push(&mut self, c: char)

Appends a single character to the end of the string.

pub fn insert_char(&mut self, index: usize, c: char)

Inserts a single character at the given character index, shifting subsequent characters right.

pub fn insert(&mut self, index: usize, us: UnicodeString)

Inserts all characters of us at the given character index, shifting subsequent characters right.

pub fn extend(&mut self, us: UnicodeString)

Appends all characters of us to the end of this string.

pub fn iter(&self) -> impl Iterator<Item = &char>

Returns an iterator over the characters in the string.
