Foundation

use-particle provides small, dependency-free primitives for classifying common particles, working with exact electric charge in thirds of the elementary charge, and looking up simple particle metadata such as spin, statistics, and approximate rest mass.

Example

use use_particle::{Particle, ParticleFamily, ParticleKind, antiparticle, charge};

let electron = Particle::new(ParticleKind::Electron);

assert_eq!(electron.family(), ParticleFamily::Lepton);
assert_eq!(charge(ParticleKind::Electron).thirds, -3);
assert_eq!(antiparticle(ParticleKind::Electron), Some(ParticleKind::Positron));

When to use directly

Choose use-particle when you need lightweight particle metadata without pulling in a broader physics or chemistry model.

Scope

• The crate stays intentionally small and does not try to be a complete particle physics database.
• Atomic structure, periodic table data, isotopes, electron shells, and chemistry concepts belong in use-chemistry.
• General constants and unit systems belong in use-constants and use-units.
• Rest masses are approximate metadata for practical examples and should not be treated as precision reference data.

Status

use-particle is a pre-1.0 crate with a deliberately small API.
