Struct LayerTileCache 

pub struct LayerTileCache { /* private fields */ }

A cache of pre-rendered RGBA tiles for no_animation layers.

Maps (tile_id, palette_group) → fully rendered RGBA tile, avoiding per-pixel calls to the tile_color closure on every frame.

Implementations

impl LayerTileCache

pub fn new() -> Self

pub fn invalidate(&mut self)

Invalidate all cached entries (call when tileset or palette changes).

pub fn get_or_insert<F>( &mut self, tile_id: u16, pal_group: u8, tile_color: &F, ) -> &RgbaTile

where F: Fn(u16, u8, u8, u8) -> Rgba,

Get a cached tile, or populate it by calling tile_color for all 64 pixels.

Trait Implementations

impl Default for LayerTileCache

fn default() -> Self

Returns the “default value” for a type.
