[][src]Module skiplist::level_generator

SkipLists use a probabilistic distribution of nodes over the internal levels, whereby the lowest level (level 0) contains all the nodes, and each level n > 0 will contain a random subset of the nodes on level n - 1.

Most commonly, a geometric distribution is used whereby the chance that a node occupies level n is p times the chance of occupying level n-1 (with 0 < p < 1).

It is very unlikely that this will need to be changed as the default should suffice, but if need be custom level generators can be implemented.

Structs

GeometricalLevelGenerator

A level generator which will produce geometrically distributed numbers.

Traits

LevelGenerator

Upon the insertion of a new node in the list, the node is replicated to high levels with a certain probability as determined by a LevelGenerator.
