Struct Particle 

pub struct Particle {
    pub kind: ParticleKind,
}

A lightweight particle wrapper that delegates to the free helper functions.

Fields

kind: ParticleKind

The underlying particle kind.

Implementations

impl Particle

pub const fn new(kind: ParticleKind) -> Self

Creates a new Particle from kind.

Examples

use use_particle::{Particle, ParticleKind};

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

assert_eq!(electron.kind, ParticleKind::Electron);
