Struct Shift 

pub struct Shift { /* private fields */ }

The accumulated effect of edits already applied, in original coordinates.

Column shifts apply only to positions on the line where the last edit ended; line shifts apply to everything after it. Tracking both is what lets several cursors edit the same line without the later ones landing in the wrong place.

Implementations

impl Shift

pub fn apply(&self, pos: Position) -> Position

Where pos — stated in the coordinates that existed before this batch — sits now.

pub fn record( &mut self, original_end_line: usize, applied_end: Position, after: Position, )

Record what an edit did.

original_end_line is in original coordinates; applied_end and after are in current ones — applied_end is where the edit’s range ended once the shift so far was applied, and after is where the replacement text left the position.
