Example: Extend the quantity and si-units packages

This example crate shows how to build a rust/PyO3 crate that uses the data types from the quantity crate in Rust to build a Python package. In the Python interface, data types are converted to classes from the si-units Python package.

Installation

maturin develop --release

Examples

from extend_quantity import ideal_gas
import si_units as si
print(ideal_gas(300 * si.KELVIN, 5 * si.LITER, 10 * si.MOL))

4.9886775708919435 MPa

Or using numpy arrays

from extend_quantity import ideal_gas_array
import si_units as si
import numpy as np
T = np.array([25, 45]) * si.CELSIUS
V = np.array([3, 5]) * si.METER**3
N = si.linspace(si.MOL, 2*si.MOL, 2)
print(ideal_gas_array(T, V, N))

array([ 826.31900987, 1058.09851279]) Pa
