Module tile 

64×64 render-tile iterator (rayon-ready; serial driver only this run). 64×64 render-tile iterator.

Splits the framebuffer into a grid of TILE_SIZE × TILE_SIZE tiles, clamped to the framebuffer boundary. Tiles are independent of each other and can be rendered in parallel (rayon-ready); this run uses a serial driver.

Structs

DirtyRegion

Tracks which tiles of the framebuffer have been modified since the last clear, enabling callers to skip re-compositing unchanged tiles.

Tile

A single render tile, identified by its top-left corner and its pixel extents (which may be smaller than DEFAULT_TILE_SIZE at boundaries).

TileIter

Iterator over the tiles covering a ClipRect, clamped to the framebuffer size.

Constants

DEFAULT_TILE_SIZE

Default tile side length in pixels.

Functions

collect_tiles

Collect all tiles covering rect into an owned Vec<Tile>.

render_tiles

Apply closure f to each tile covering rect.

tiles_for

Return an iterator over DEFAULT_TILE_SIZE-sized tiles covering rect, clamped to the framebuffer dimensions fb_w × fb_h.
