# SDSL - Succinct Data Structure Library (vgteam fork)

## This fork

This is [vgteam's](https://github.com/vgteam) fork of the Succinct Data Structure Library (SDSL).
As [SDSL 2](https://github.com/simongog/sdsl-lite) is no longer maintained, vgteam tools and libraries will depend on this until SDSL 3 is released.

## Major changes

* Switched from C++11 to C++14.
* `sd_vector` improvements:
  * `sd_vector::one_iterator`: Iterator over set bits.
  * Predecessor and successor queries.
  * Defined semantics for an `sd_vector` encoding a multiset of integers.
  * Smaller size due to a better formula for the number of buckets.
* `rle_vector`: A run-length encoded bitvector.
* Proper support for 64-bit ARM.
* Support for the [simple-sds serialization format](https://github.com/jltsiren/simple-sds/blob/main/SERIALIZATION.md):
  * `int_vector<0>` corresponds to `IntegerVector`.
  * `int_vector<1>` corresponds to `BitVector`.
  * `int_vector<8>` and `int_vector<64>` correspond to vectors of bytes and elements.
  * `sd_vector<>` corresponds to `SparseVector`.
