Package keys is a composable framework for constructing badger keys from fields of events.

GetBackend returns a reasonably configured badger.Backend.

GetCounterKey returns the proper counter key for a given event ID.

GetIndexKeysForEvent generates all the index keys required to filter for events.

GetTagKeyPrefix returns tag index prefixes based on the initial field of a tag.

MakeAccessEvent generates an *AccessEvent from an event ID and serial.

PrepareQueries analyses a filter and generates a set of query specs that produce key prefixes to search for in the badger key indexes.
