Cargo Features

[dependencies]
pthash = { version = "0.4.0", default-features = false, features = ["check", "rayon", "default_minimalities", "minimal", "nonminimal", "default_hash_sizes", "hash64", "hash128", "default_encoders", "dictionary_dictionary", "elias_fano"] }

default = default_encoders, default_hash_sizes, default_minimalities

These default features are set whenever pthash is added without default-features = false somewhere in the dependency tree.

check

Enables sux ^0.3.1 and thiserror ^1.0.48

Affects utils::ViolatedInvariant, utils::check…

rayon

Enables rayon

Affects pthash::Phf.par_build_in_internal_memory_from_bytes…

default_minimalities default = minimal, nonminimal

The following feature groups trigger instantiation of C++ template for their cartesian product. By default, these are 2 PHF types × 2 minimalities × 2 hash sizes × 3 encoders = 24 instances

Minimalities

minimal default_minimalities

Affects minimality::Minimal…

nonminimal default_minimalities

Affects minimality::Nonminimal…

default_hash_sizes default = hash128, hash64

Hash sizes

hash64 default_hash_sizes hash128?

Affects encoders::Encoder, hashing::MurmurHash2_64, encoders::Encoder…

hash128 default_hash_sizes = hash64

implementation of MurmurHash2_128 depends on MurmurHash2_64
