Trait EngineeringRepr

pub trait EngineeringRepr<T: EQSupported<T>> {
    // Required methods
    fn to_eng(self, sig_figures: usize) -> DisplayAdapter<T>;
    fn to_rkm(self, sig_figures: usize) -> DisplayAdapter<T>;
}

A convenience trait for outputting integers directly in engineering notation.

DisplayAdapter implements Display, so you can use the returned adapter directly in a formatting macro.

Required Methods

fn to_eng(self, sig_figures: usize) -> DisplayAdapter<T>

Outputs a number in engineering notation

A request for 0 significant figures outputs exactly as many digits are necessary to maintain precision.

use engineering_repr::EngineeringRepr as _;
assert_eq!("123k", 123456.to_eng(3));
assert_eq!("123.4k", 123456.to_eng(4));
assert_eq!("123.456k", 123456.to_eng(0));

Panics

If the value could not be rendered

fn to_rkm(self, sig_figures: usize) -> DisplayAdapter<T>

Outputs a number in RKM notation

A request for 0 significant figures outputs exactly as many digits are necessary to maintain precision.

use engineering_repr::EngineeringRepr as _;
assert_eq!("123k", 123456.to_rkm(3));
assert_eq!("123k4", 123456.to_rkm(4));
assert_eq!("123k456", 123456.to_rkm(0));

Panics

If the value could not be rendered
