ExPmtiles.Cache.Operations (ExPmtiles v0.3.4)
View SourcePure business logic for PMTiles cache operations.
This module contains all the tile fetching and caching logic without any GenServer-specific code. All functions are pure and easily testable.
The architecture is simplified: each request process does its own work, checking file-based caches and fetching from storage as needed. No inter-process coordination is needed because the filesystem handles concurrent access naturally.
