Struct rust_3d::Positive

pub struct Positive { /* fields omitted */ }

Positive, a wrapper for a f64 value, ensuring it is always > 0

Methods

impl Positive

pub fn one() -> Positive

Creates a new Positive with value 1

pub fn get(&self) -> f64

Returns the wrapped value

pub fn sqrt(&self) -> Positive

Returns the square root
