pub struct Grid { /* private fields */ }

Available on crate feature terminal only.

Grid with VecDeque-based scrollback

Layout: [scrollback_rows… | visible_rows…] row0() calculates where visible area starts

Implementations

impl Grid

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

Create a new grid

pub fn size(&self) -> Size

Get grid size

pub fn scrollback(&self) -> usize

Get current scrollback offset

pub fn scrollback_len(&self) -> usize

Get maximum scrollback length

pub fn set_scrollback(&mut self, offset: usize)

Set scrollback offset

pub fn scroll_screen_up(&mut self, n: usize)

Scroll screen up (view older content)

pub fn scroll_screen_down(&mut self, n: usize)

Scroll screen down (view newer content)

pub fn visible_rows(&self) -> impl Iterator<Item = &Row>

Get visible rows iterator

pub fn cell(&self, row: usize, col: usize) -> Option<&Cell>

Get cell at position (relative to visible area)

pub fn cell_mut(&mut self, row: usize, col: usize) -> Option<&mut Cell>

Get mutable cell at position (relative to current visible bottom)

pub fn row(&self, row: usize) -> Option<&Row>

pub fn scroll_up(&mut self, count: usize)

Scroll content up (add new line at bottom, old line goes to scrollback)

pub fn resize(&mut self, rows: usize, cols: usize)
