Struct Buffer 

pub struct Buffer {
    pub size: Size,
    pub cells: Vec<Cell>,
}

字符格缓冲区

Fields

size: Size

cells: Vec<Cell>

Implementations

impl Buffer

pub fn new(size: Size) -> Self

Creates a new buffer of the given size, filled with default (blank) cells.

pub fn resize(&mut self, size: Size)

Resizes the buffer, discarding all existing content.

pub fn clear(&mut self)

Resets every cell in the buffer to its default (blank) state.

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

Returns a mutable reference to the cell at (x, y), or None if out of bounds.

pub fn write_text(&mut self, pos: Pos, clip: Rect, text: &str, style: &Style)

写入文本到缓冲区（支持宽字符）

CJK 等宽字符占 2 cell，第二格标记为 continuation。

pub fn draw_border(&mut self, rect: Rect, border: Border, style: &Style)

在指定 rect 边框绘制边框字符

pub fn all_ops(&self) -> Vec<DiffOp>

返回所有 cell 的 DiffOp（跳过 continuation）

pub fn diff(&self, next: &Buffer) -> Vec<DiffOp>

比较两个 buffer，返回所有变更的 DiffOp（跳过 continuation）

支持不同尺寸的 buffer 比较，以 next 的尺寸为基准输出。
