Limits for retained image pixels and parsed SVGs. Set this record as Emerge.Config.Assets.cache. Budgets apply separately to each renderer.

%Emerge.Config{
  assets: %Emerge.Config.Assets{
    cache: %Emerge.Config.AssetCache{max_entries: 32, max_bytes: 32 * 1024 * 1024}
  }
}

Fields

• max_entries — maximum retained decoded-image entries, including rasterized SVG sizes; defaults to 256.
• max_bytes — retained decoded-pixel budget in bytes; defaults to 268_435_456 (256 MiB). This is not compressed file size.
• svg_tree_max_entries — maximum retained parsed SVGs; defaults to 64. One parsed SVG can be reused to draw multiple sizes.
• svg_tree_max_bytes — estimated parsed-SVG storage budget in bytes; defaults to 16_777_216 (16 MiB), separate from rendered pixels.

All values are non-negative integers. A zero entry/byte limit disables retention in the corresponding cache; images still load and draw. Limits do not bound peak decoding memory, fonts or total application memory. These fields require a new viewport to change. See Use assets for cache tuning.
