Struct Cursors 

pub struct Cursors { /* private fields */ }

Collection of cursors with multi-cursor support

Implementations

impl Cursors

pub fn new() -> Self

Create a new cursor collection with one cursor at position 0

pub fn primary(&self) -> &Cursor

Get the primary cursor

pub fn primary_mut(&mut self) -> &mut Cursor

Get the primary cursor mutably

pub fn primary_id(&self) -> CursorId

Get the primary cursor ID

pub fn get(&self, id: CursorId) -> Option<&Cursor>

Get a cursor by ID

pub fn get_mut(&mut self, id: CursorId) -> Option<&mut Cursor>

Get a cursor by ID mutably

pub fn add(&mut self, cursor: Cursor) -> CursorId

Add a new cursor and return its ID

pub fn insert_with_id(&mut self, id: CursorId, cursor: Cursor)

Insert a cursor with a specific ID (for undo/redo)

pub fn remove(&mut self, id: CursorId) -> Option<Cursor>

Remove a cursor by ID

pub fn remove_secondary(&mut self)

pub fn ids(&self) -> Vec<CursorId>

Get all cursor IDs

pub fn iter(&self) -> impl Iterator<Item = (CursorId, &Cursor)>

Get all cursors as a slice

pub fn count(&self) -> usize

pub fn map<F>(&mut self, f: F)

where F: FnMut(&mut Cursor),

pub fn adjust_for_edit( &mut self, edit_pos: usize, old_len: usize, new_len: usize, )

Adjust all cursors after an edit

pub fn normalize(&mut self)

Normalize cursors: merge overlapping selections, remove duplicates

pub fn positions(&self) -> Vec<usize>

Get all cursor positions (for rendering)

pub fn selections(&self) -> Vec<Range<usize>>

Get all selection ranges (for rendering)
