Struct RenderGrid 

pub struct RenderGrid {
    pub cells: Vec<Vec<Cell>>,
    pub width: u32,
    pub height: u32,
}

A 2D grid of Cells with explicit width × height dimensions.

Filters operate on owned RenderGrids and return new owned grids per AD-002 (immutable transformations). Construction normalizes ragged row vectors to a rectangular shape padded with Cell::blank so downstream filters can assume cells[y].len() == width for every row.

Allocated as Vec<Vec<Cell>> rather than a single flat Vec<Cell> because the filter implementations (transpose, rotate, flip) work row-major and benefit from being able to .swap(), .reverse(), and .collect() per-row without index arithmetic.

Fields

cells: Vec<Vec<Cell>>

Cells in row-major order. cells[y][x] is the cell at column x, row y. Every row is exactly width cells long after construction.

width: u32

Number of columns.

height: u32

Number of rows.

Implementations

impl RenderGrid

pub fn empty() -> Self

Construct an empty grid (0×0).

pub fn blank(width: u32, height: u32) -> Self

Construct a rectangular grid sized width × height, filled with blank cells.

pub fn from_rows(rows: Vec<Vec<Cell>>) -> Self

Build a grid from a vector of rows; ragged rows are padded with Cell::blank up to the longest row’s length.

pub fn from_text_rows(rows: &[String]) -> Self

Construct a grid from a multi-line &str. Each line is one row; each character is one cell with default color. Convenient for tests and the FLF/TLF render pipeline’s Vec<String> row output.
