Package epochs implements time-based feeds using epochs as index and provide sequential as well as concurrent lookup algorithms.

Package sequence provides implementation of sequential indexing for time-based feeds this feed type is best suited for - version updates - followed updates - frequent or regular-interval updates.

package testing provides tests for update and resolution of time-based feeds.

FromChunk parses out the wrapped chunk.

Id calculates the feed id from a topic and an index.

Latest looks up the latest update of the feed after is a unix time hint of the latest known update.

New constructs an epoch based feed from a keccak256 digest of a plaintext topic and an ether address.

NewGetter constructs a feed Getter.

NewPutter constructs a feed Putter.

NewUpdate creates an update from an index, timestamp, payload and signature.

Feed is representing an epoch based feed.

Getter encapsulates a chunk Getter getter and a feed and provides non-concurrent lookup methods.

Putter encapsulates a chunk store putter and a Feed to store feed updates.

Update represents an update instance of a feed, i.e., pairing of a Feed with an Epoch.

Factory creates feed lookups for different types of feeds.

Index is the interface for feed implementations.

Lookup is the interface for time based feed lookup.

Updater is the generic interface f.

Type enumerates the time-based feed types.
