How To Install libtsl-hopscotch-map-dev on Kali Linux

Introduction

In this tutorial we learn how to install libtsl-hopscotch-map-dev on Kali Linux.

What is libtsl-hopscotch-map-dev

libtsl-hopscotch-map-dev is:

The hopscotch-map library is a C++ implementation of a fast hash map and hash set using open-addressing and hopscotch hashing to resolve collisions. It is a cache-friendly data structure offering better performances than std::unordered_map in most cases and is closely similar to google::dense_hash_map while using less memory and providing more functionalities.

The library provides the following main classes: tsl::hopscotch_map, tsl::hopscotch_set, tsl::hopscotch_pg_map and tsl::hopscotch_pg_set. The first two are faster and use a power of two growth policy, the last two use a prime growth policy instead and are able to cope better with a poor hash function. Use the prime version if there is a chance of repeating patterns in the lower bits of your hash (e.g. you are storing pointers with an identity hash function).

In addition to these classes the library also provides tsl::bhopscotch_map, tsl::bhopscotch_set, tsl::bhopscotch_pg_map and tsl::bhopscotch_pg_set. These classes have an additional requirement for the key, it must be LessThanComparable, but they provide a better asymptotic upper bound. Nonetheless if you don’t have specific requirements (risk of hash DoS attacks), tsl::hopscotch_map and tsl::hopscotch_set should be sufficient in most cases and should be your default pick as they perform better in general.

There are three methods to install libtsl-hopscotch-map-dev on Kali Linux. We can use apt-get, apt and aptitude. In the following sections we will describe each method. You can choose one of them.
