Struct Buffer 

pub struct Buffer { /* private fields */ }

A rectangular grid of terminal cells.

Stores styled text content for rendering to a terminal. Use set_string and set_style to modify the buffer contents.

Implementations

impl Buffer

pub fn scroll_up(&mut self, amount: u16)

Scrolls content up by the given number of lines.

Lines shifted off the top are discarded; new lines at the bottom are filled with empty cells.

pub fn scroll_down(&mut self, amount: u16)

Scrolls content down by the given number of lines.

Lines shifted off the bottom are discarded; new lines at the top are filled with empty cells.

pub fn width(&self) -> u16

Returns the buffer width in cells.

pub fn height(&self) -> u16

Returns the buffer height in cells.

pub fn new(width: u16, height: u16) -> Buffer

Creates a new buffer with the given dimensions.

pub fn get_mut(&mut self, x: u16, y: u16) -> Option<&mut Cell>

Returns a mutable reference to the cell at the given position.

pub fn row_remaining_mut(&mut self, x: u16, y: u16) -> Option<&mut [Cell]>

Returns a mutable slice of cells from position (x, y) to the end of the row.

pub fn set_style(&mut self, area: Rect, style: Style)

pub fn set_string( &mut self, x: u16, y: u16, string: &str, style: Style, ) -> (u16, u16)

Writes a styled string at the given position.

Returns the cursor position after writing.

pub fn set_stringn( &mut self, x: u16, y: u16, string: &str, max_width: usize, style: Style, ) -> (u16, u16)

Writes a styled string with a maximum width.

Returns the cursor position after writing.
