Implementation of a bimap data structure, i.e. an unordered
collection of key-value pairs. The notable difference to
hashmap
is that the mapping is not only
$$f: keys -> values,$$
but also
$$f: values -> keys.$$
Inserting and accessing is amortized in O(1).
bimap
wraps a boost::bimap
using Rcpp modules.
.map

object representing a mapping
.key.class
