Struct termwiz::surface::change::ChangeSequence

pub struct ChangeSequence { /* private fields */ }

Keeps track of a run of changes and allows reasoning about the cursor position and the extent of the screen that the sequence will affect. This is useful for example when implementing something like a LineEditor where you don’t want to take control over the entire surface but do want to be able to emit a dynamically sized output relative to the cursor position at the time that the editor is invoked.

Implementations

impl ChangeSequence

pub fn new(rows: usize, cols: usize) -> Self

pub fn consume(self) -> Vec<Change>

pub fn current_cursor_position(&self) -> (usize, isize)

Returns the cursor position, (x, y).

pub fn move_to(&mut self, (cursor_x, cursor_y): (usize, isize))

pub fn render_height(&self) -> usize

Returns the total number of rows affected

pub fn add_changes(&mut self, changes: Vec<Change>)

pub fn add<C: Into<Change>>(&mut self, change: C)
