Struct Cursor

pub struct Cursor<'a> {
    pub no_eol: bool,
    /* private fields */
}

Cursor (as in the terminal’s cursor) exposes various functions that modify the Buffer (Buffer for new line or for editing history, that’s transparent to Cursor) and maintain the position on the terminal that the actual cursor needs to be drawn.

Fields

no_eol: bool

Implementations

impl<'a> Cursor<'a>

pub fn new_with_divider(divider: &'a dyn EditorRules) -> Self

pub fn curr_grapheme(&self) -> usize

pub fn insert_around(&mut self, buf: &mut Buffer, right: bool, count: usize)

pub fn move_cursor_to(&mut self, buf: &Buffer, pos: usize)

Moves the cursor to pos. If pos is past the end of the buffer, it will be clamped.

pub fn get_words_and_cursor_position( &self, buf: &Buffer, ) -> (Vec<(usize, usize)>, CursorPosition)

pub fn reset(&mut self, buf: &mut Buffer)

pub fn delete_until_cursor(&mut self, buf: &mut Buffer, start: usize)

pub fn insert_char_after_cursor(&mut self, buf: &mut Buffer, c: char)

pub fn insert_str_after_cursor(&mut self, buf: &mut Buffer, s: &str)

pub fn insert_chars_after_cursor(&mut self, buf: &mut Buffer, cs: &[char])

pub fn delete_before_cursor(&mut self, buf: &mut Buffer)

pub fn move_cursor_to_end_of_line(&mut self, buf: &Buffer)

pub fn is_at_beginning_of_word_or_line(&self, buf: &Buffer) -> bool

Trait Implementations

impl<'a> Clone for Cursor<'a>

fn clone(&self) -> Cursor<'a>

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
