A quantity is a common super trait for types that represent units of measurement.

Required methods

fn pack(_: f64) -> Self

Create a new instance of self by wrapping a value

fn unpack(self) -> f64

Unpack a wrapped value without any error checking.

fn unwrap(self) -> f64

Unwrap the value from the new type and check for validity, panic if contents are invalid.

fn into_option(self) -> Option<f64>

Convert into an option that is None if the content is invalid.
