EDA.Cache.Channel (EDA v0.3.0)

Copy Markdown View Source

ETS-based cache for Discord channels.

Uses composite keys {guild_id, channel_id} for O(guild_size) lookups via for_guild/1 instead of full table scans. A reverse index table maps channel_id to guild_id for efficient single-channel lookups.

DM channels use nil as their guild_id.
