Module kitsune_p2p_dht::region_set

A RegionSet is a compact representation of a set of Regions – the RegionCoords defining the regions, and their associated RegionData.

Currently we have only one scheme for specifying RegionSets, called “LTCS”. “LTCS” is an acronym standing for “Logarithmic Time, Constant Space”, and it refers to our current scheme of partitioning spacetime during gossip, which is to use a constant number of SpaceSegments (8..16) and a logarithmically growing number of TimeSegments, with larger segments to cover older times. In the future we may have other schemes.

Structs

• RegionCoordSetLtcs
  A compact representation of a set of RegionCoords. The TelescopingTimes generates all relevant TimeSegments, and the SpaceSegments are implied by the ArqBoundsSet.
• RegionSetLtcs
  Implementation for the compact LTCS region set format which gets sent over the wire. The coordinates for the regions are specified by a few values. The data to match the coordinates are specified in a 2D vector which must correspond to the generated coordinates.

Enums

• RegionSet
  The generic definition of a set of Regions. The current representation is very specific to our current algorithm, but this is an enum to make room for a more generic representation, e.g. a simple Vec<Region>, if we want a more intricate algorithm later.
