pyrsistent - Persistent/Immutable/Functional data structures for Python

•    Python

---

Pyrsistent is a number of persistent collections (by some referred to as functional data structures). Persistent in the sense that they are immutable. All methods on a data structure that would normally mutate it instead return a new copy of the structure containing the requested updates. The original structure is left untouched.

cosmos - Algorithms that run our universe | Your personal library of every algorithm and data structure code that you will ever encounter | Ask us anything at our forum

•    C++

---

Cosmos is your personal offline collection of every algorithm and data structure one will ever encounter and use in a lifetime. This provides solutions in various languages spanning C, C++, Java, JavaScript, Swift, Python, Go and others. This work is maintained by a community of hundreds of people and is a massive collaborative effort to bring the readily available coding knowledge offline.

This is a collection of different data structures and utilities, implemented in JavaScript. Its written and tested using Node.js which is also the target platform.CircularBuffer - A data structure that uses a single, fixed-size buffer as if it were connected end-to-end. When the buffer is filled, new data is written starting at the beginning of the buffer and overwriting the old.

bloom-filter-scala - Bloom filter for Scala, the fastest for JVM

•    Scala

---

"A Bloom filter is a space-efficient probabilistic data structure that is used to test whether an element is a member of a set. False positive matches are possible, but false negatives are not. In other words, a query returns either "possibly in set" or "definitely not in set". Elements can be added to the set, but not removed," says Wikipedia. Warning: These are synthetic benchmarks in isolated environment. Usually the difference in throughput and latency is bigger in production system because it will stress the GC, lead to slow allocation paths and higher latencies, trigger the GC, etc.

lens - A utility for working with nested data structures.

•    Elixir

---

A utility for working with nested data structures. Take a look at Nested data structures with functional lenses for a gentler introduction. In 0.6.0 the function Lens.get got removed. The reason was that it was very easy to create a bug where a list was treated as a single element or vice-versa. Wherever you used Lens.get you now should either use Lens.one! if the invocation should always return exactly one element (this will crash if there is any other number of elements) or Lens.to_list and match on the result if you want to behave differently for different numbers of elements.

roaringbitmap - Roaring Bitmap in Cython

•    Python

---

A roaring bitmap is an efficient compressed datastructure to store a set of integers. A Roaring bitmap stores a set of 32-bit integers in a series of arrays and bitmaps, whichever takes the least space (which is always 2 ** 16 bits or less). This datastructure is useful for storing a large number of integers, e.g., for an inverted index used by search engines and databases. In particular, it is possible to quickly compute the intersection of a series of sets, which can be used to implement a query as the conjunction of subqueries.
