Expand description

Struct capable of calculating the LCA of 2 nodes in a TaxonTree, using RMQ.

Fields§

§first_occurences: HashMap<TaxonId, usize>

Keeps track in which step of the euler tour a given taxon is encountered for the first time.

§euler_tour: Vec<TaxonId>

Contains the taxons in the order of an Eulerian tour.

§rmq_info: RMQ<usize>

The RMQ to which the LCA corresponds.
