Succinct data structures and other Rust libraries and programs by Piotr Beling.

Included libraries:

• ph (crate, doc) - minimal perfect hash functions (PHast, FMPH and FMPHGO);
• csf (crate, doc) - compressed static functions (maps);
• cseq (crate, doc) - compact sequences (like Elias-Fano);
• minimum_redundancy (crate, doc) - encode and decode data with binary or non-binary Huffman coding;
• bitm (crate, doc) - bit and bitmap manipulation;
• seedable_hash (crate, doc) - seedable hashers,
• binout (crate, doc) - binary encoding, decoding, serialization, deserialization;
• fsum (crate, doc) - calculate accurate sum of floats;
• dyn_size_of (crate, doc) - calculate memory consumed by variables, including the memory allocated on heap,
• butils (crate, doc) - (internal) utilities shared by software included in BSuccinct.

Included programs:

• mphf_benchmark (crate, doc) - benchmarking minimal perfect hash functions,
• csf_benchmark (crate, doc) - benchmarking compressed static functions,
• cseq_benchmark (crate, doc) - benchmarking compact sequences,
• coding_benchmark (crate, doc) - benchmarking Huffman coding crates.

Installation

Programs can be compiled and installed from sources. To do this, a Rust compiler is needed. The easiest way to obtain the compiler along with other necessary tools (like cargo) is to use rustup.

Please follow the instructions at https://www.rust-lang.org/tools/install.

Installing rust programs

Once Rust is installed, to compile and install a program from sources and with native optimizations, just execute:

RUSTFLAGS="-C target-cpu=native" cargo install <program_name>

for example

RUSTFLAGS="-C target-cpu=native" cargo install mphf_benchmark

Platforms with 32-bit addressing

For portability, BSuccinct components compile and run on platforms with 32-bit addressing (like wasm32). However, they are optimized primarily with 64-bit CPUs in mind.
