source§fn is_boundary(&self) -> bool
fn is_boundary(&self) -> bool
Check if cursor position is at a codepoint boundary.
source§fn prev(&mut self) -> Option<usize>
fn prev(&mut self) -> Option<usize>
Move cursor to previous codepoint boundary, if it exists.
Returns previous codepoint as usize offset.
source§fn next(&mut self) -> Option<usize>
fn next(&mut self) -> Option<usize>
Move cursor to next codepoint boundary, if it exists.
Returns current codepoint as usize offset.
source§fn peek_next_codepoint(&self) -> Option<char>
fn peek_next_codepoint(&self) -> Option<char>
Get the next codepoint after the cursor position, without advancing
the cursor.
source§fn prev_codepoint(&mut self) -> Option<char>
fn prev_codepoint(&mut self) -> Option<char>
Return codepoint preceding cursor offset and move cursor backward.
source§fn next_codepoint(&mut self) -> Option<char>
fn next_codepoint(&mut self) -> Option<char>
Return codepoint at cursor offset and move cursor forward.
source§fn at_or_next(&mut self) -> Option<usize>
fn at_or_next(&mut self) -> Option<usize>
Return current offset if it’s a boundary, else next.
source§fn at_or_prev(&mut self) -> Option<usize>
fn at_or_prev(&mut self) -> Option<usize>
Return current offset if it’s a boundary, else previous.
