hodgepodge

Ready-made Rust datasets for teaching, prototypes, simulations, and test fixtures. 56 compact enums cover colors, chemistry, anatomy, biology, geography, geologic time, calendars, and games. Optional taxonomy adds 80,868 animal species.

Rust 1.71+. No default dependencies.

Quick start

[dependencies]
hodgepodge = "0.4"

use hodgepodge::{Bone, Codon, Element, IsoCountry, States};

assert_eq!(Element::from_symbol("Fe"), Some(Element::Iron));
assert_eq!(Bone::COUNT, 206);
assert_eq!(Bone::LeftFemur.mirrored(), Bone::RightFemur);
assert_eq!(States::NewYork.postal_abbreviation(), "NY");
assert_eq!(IsoCountry::Canada.canadian_provinces().count(), 13);
assert_eq!(Codon::Aug.sequence(), "AUG");

for element in Element::ALL {
    println!("{}: {}", element.label(), element.atomic_number());
}

Every enum dataset supports comparison, hashing, display, parsing, ALL, COUNT, label(), and source/scope metadata through INFO. Parsing accepts canonical variant names without spaces, ignoring ASCII case; named constructors handle external codes. Relationships connect bones to regions, epochs to periods, codons to amino acids, countries to subdivisions, and more.

Optional features

Feature Adds
serde Serialization for dataset enums, cards, codon meanings, and taxonomy keys
rand Uniform sampling and deck shuffling with a caller-supplied rand 0.9 RNG
strum Iterator/count traits; also enabled by legacy enum-iter and enum-count
taxonomy Bundled animal records and nested species paths; no runtime network access

Enable features with hodgepodge = { version = "0.4", features = ["taxonomy"] }.

Animal taxonomy

# #[cfg(feature = "taxonomy")]
# {
use hodgepodge::taxonomy::{animalia, Species};
use animalia::chordata::mammalia::carnivora::felidae::panthera;

let lion = panthera::Leo;
assert_eq!(lion, Species::PantheraLeo);
assert_eq!(lion.taxon().parent(), Some(panthera::TAXON));
println!("{}", lion.taxon().wikipedia_url().unwrap());
# }

This dated selection includes every source ancestor, not every animal species. Taxonomy adds substantial compile/documentation cost; its source files remain in the download even when disabled. For persistent taxonomy identity, use Taxon::key(); serialized enum names/indexes may change between snapshots.
