Implementations

impl<'a> StringCursor<'a>

pub fn new(text: &'a str) -> StringCursor<'a>

Create a new cursor.

Trait Implementations

impl<'a> Debug for StringCursor<'a>

fn fmt(&self, f: &mut Formatter<'_>) -> Result<(), Error>

Formats the value using the given formatter.

impl<'a> EditableTextCursor<&'a String> for StringCursor<'a>

fn set(&mut self, position: usize)

Set cursor position.

fn pos(&self) -> usize

Get cursor position.

fn is_boundary(&self) -> bool

Check if cursor position is at a codepoint boundary.

fn prev(&mut self) -> Option<usize>

Move cursor to previous codepoint boundary, if it exists. Returns previous codepoint as usize offset.

fn next(&mut self) -> Option<usize>

Move cursor to next codepoint boundary, if it exists. Returns current codepoint as usize offset.

fn peek_next_codepoint(&self) -> Option<char>

Get the next codepoint after the cursor position, without advancing the cursor.

fn prev_codepoint(&mut self) -> Option<char>

Return codepoint preceding cursor offset and move cursor backward.

fn next_codepoint(&mut self) -> Option<char>

Return codepoint at cursor offset and move cursor forward.

fn at_or_next(&mut self) -> Option<usize>

Return current offset if it’s a boundary, else next.

fn at_or_prev(&mut self) -> Option<usize>

Return current offset if it’s a boundary, else previous.
