Trait TypoScale 

pub trait TypoScale<T>
where
    T: Default,
{
    // Required method
    fn typoscale(&self) -> f64;

    // Provided methods
    fn int_typoscale(&self) -> usize { ... }
    fn int_typoscale_floor(&self) -> usize { ... }
    fn fraction_str(&self) -> String { ... }
}

By default, on the standard types like usize, this yields 1, 1 1⁄10, 1 3⁄10, 1 ½, 1 7⁄10, 2, 2 ⅕, 2 ⅗, 3, 3 ⅖, 4, 4 ½, 5 ⅕, 6, 6 9⁄10, 8, 9 1⁄10, 10 ½, 12 1⁄10, 13 9⁄10, 16, 18 3⁄10, 21 1⁄10, 24 ⅕, 27 ⅘, 32, 36 7⁄10, 42 ⅕, 48 ½, 55 7⁄10, 64, 73 ½, 84 ⅖, 97, 111 ⅖, 128, 147, 168 ⅘, 194, 222 ⅘, 256, 294, 337 7⁄10, 388, 445 7⁄10, 512, 588 1⁄10, 675 ½, 776, 891 ⅖, 1024, 1176 ⅕, 1351 1⁄10, 1552, 1782 ⅘, 2048, 2352 ½, 2702 3⁄10, 3104 1⁄10, 3565 7⁄10, 4096, 4705, 5404 7⁄10, 6208 3⁄10…

If you want the traditional European typographic scale, you want iter::TypoScaleLcgIterator.

Required Methods

fn typoscale(&self) -> f64

converts a positive integer index to its equivalent value on the typographic scale.

Provided Methods

fn int_typoscale(&self) -> usize

converts a positive integer index to its equivalent value on the typographic scale. (rounded to nearest)

fn int_typoscale_floor(&self) -> usize

converts a positive integer index to its equivalent value on the typographic scale. (floored)

fn fraction_str(&self) -> String

returns a string representation of the whole and fractional components of the typographic scale value for a positive integer
