Function spglib::hall_number_from_symmetry

pub fn hall_number_from_symmetry(
    rotations: &mut [[[i32; 3]; 3]], 
    translations: &mut [[f64; 3]], 
    symprec: f64
) -> i32

Returns the hall number for a given set of symmetry operations

Examples

Get the hall number for a BCC cell in a roundabout way

use spglib as spg;
let dataset = Dataset::new(&mut bcc_cell, 1e-5);
let mut rotations = dataset.rotations.clone();
let mut translations = dataset.translations.clone();
let hall_number =
    spg::hall_number_from_symmetry(&mut rotations, &mut translations, 1e-5);
assert_eq!(hall_number, dataset.hall_number);
