Struct ElementaryCharge 

pub struct ElementaryCharge {
    pub thirds: i8,
}

An exact electric charge expressed in thirds of the elementary charge.

Fields

thirds: i8

Charge measured in thirds of the elementary charge.

impl ElementaryCharge

pub const fn new_thirds(thirds: i8) -> ElementaryCharge

Creates a charge from thirds of the elementary charge.

pub const fn neutral() -> ElementaryCharge

Returns a neutral charge.

pub const fn positive_one() -> ElementaryCharge

Returns a +1e charge.

pub const fn negative_one() -> ElementaryCharge

Returns a -1e charge.

pub fn as_elementary_units(self) -> f64

Returns the charge in elementary-charge units.
