Struct TileSet 

pub struct TileSet { /* private fields */ }

A set of decoded tiles, indexed by tile number.

Implementations

impl TileSet

pub fn from_2bpp(data: &[u8]) -> Self

Create a tileset by decoding 2bpp tile data. The data length must be a multiple of 16 (bytes per tile).

pub fn blank(count: usize) -> Self

Create an empty tileset with count blank tiles.

pub fn get(&self, index: usize) -> &Tile

Get a tile by index. Returns blank tile if out of bounds.

pub fn len(&self) -> usize

Number of tiles in this set.

pub fn is_empty(&self) -> bool

Whether this tileset is empty.

pub fn set(&mut self, index: usize, tile: Tile)

Replace a tile at the given index.

pub fn load_2bpp_at(&mut self, start_tile: usize, data: &[u8])

Load raw 2bpp data into the tileset starting at tile index start_tile. Overwrites existing tiles.

pub fn from_1bpp(data: &[u8]) -> Self

Decode 1bpp tile data (8 bytes per tile, 1 bit per pixel). Color 0 → palette index 0, color 1 → palette index 3 (black).

pub fn from_4bpp(data: &[u8]) -> Self

Decode GBA-style 4bpp tile data (32 bytes per tile, 2 bitplanes × 16 bytes each).

Each tile requires 32 bytes. The first 16 bytes are bitplane 0, the next 16 bytes are bitplane 1. Each bitplane uses standard 2bpp encoding (2 bytes per row, low byte then high byte), contributing 2 bits per pixel. Combined they give 4 bits per pixel (0–15), stored in Tile::pixels as u8.

pub fn from_rgba(pixels: &[Rgba], tile_count: usize) -> Self

Create a tileset from flat RGBA pixel data.

pixels should contain tile_count * 64 RGBA values (8×8 pixels per tile). Tiles are laid out sequentially: pixels[0..64] = tile 0, pixels[64..128] = tile 1, etc. Each tile is stored as an RgbaTile in the internal rgba_tiles buffer for direct rendering. The tiles field contains blank dummy tiles for backward compatibility.

pub fn tile_format(&self) -> TileFormat

Return the tile format of this tileset.

pub fn get_rgba(&self, index: usize) -> Option<&RgbaTile>

Get an RGBA tile by index. Returns None if the tileset is not in TileFormat::FullColor mode or the index is out of bounds.

Trait Implementations

Performs copy-assignment from source.

impl Debug for TileSet

fn fmt(&self, f: &mut Formatter<'_>) -> Result
