//! Rs-measures version of the example `base.rs` of the crate `uom` version 0.35.0.
//! Example showing how to create a set of `Quantity` type aliases for a different set of base
//! units.
/*
Rs-measures will print:
length: 1 m
length: 1 cm
1 m + 1 cm = 1.01 m
1 cm + 1 m = 101 cm
1 cm / 15 s = 0.06666667 cm/s

UOM will print:
length: 1.0 m^1
length: 1.0 cm^1
1.0 m^1 + 1.0 cm^1 = 1.01 m^1
1.0 cm^1 + 1.0 m^1 = 101.0 cm^1
1.0 cm^1 / 15.0 s^1 = 0.06666667 cm^1 s^-1

After replacing every `{:?}` with `{}`, Rs-measures will print the same.
UOM will emit compilation error.
