Module webrender::texture_cache

Structs

• CacheAllocParams 🔒
  Container struct for the various parameters used in cache allocation.
• CacheEntry
• EvictionNotice
• SharedTextures 🔒
  A set of lazily allocated, fixed size, texture arrays for each format the texture cache supports.
• TextureCache
  General-purpose manager for images in GPU memory. This includes images, rasterized glyphs, rasterized blobs, cached render tasks, etc.
• TextureCacheConfig
  Startup parameters for the texture cache.
• TextureParameters

Enums

• AutoCacheEntryMarker
• BudgetType 🔒
  The different budget types for the texture cache. Each type has its own memory budget. Once the budget is exceeded, entries with automatic eviction are evicted. Entries with manual eviction share the same budget but are not evicted once the budget is exceeded. Keeping separate budgets ensures that we don’t evict entries from unrelated textures if one texture gets full.
• EntryDetails
  Items in the texture cache can either be standalone textures, or a sub-rect inside the shared cache.
• Eviction
  Describes the eviction policy for a given entry in the texture cache.
• ManualCacheEntryMarker
• TargetShader
  Information about which shader will use the entry.
• TextureCacheHandle
  A texture cache handle is a weak reference to a cache entry.

Constants

• TEXTURE_REGION_DIMENSIONS
  The size of each region in shared cache texture arrays.
