Struct Fingerprint 

pub struct Fingerprint {
    pub buses: usize,
    pub base_mva: i64,
    pub degrees: Vec<usize>,
    pub impedances: Vec<i64>,
    pub hvdc: usize,
    pub load_p: i64,
    pub load_q: i64,
}

What makes two files the same case.

The whole struct is the bucketing key. It deliberately leaves out the load, generator and shunt counts: formats merge and split devices at a bus (PSS/E states three loads where MATPOWER states one bus demand), so those counts differ between honest siblings while the demand they sum to does not.

Fields

buses: usize

base_mva: i64

degrees: Vec<usize>

Sorted bus degrees over in-service branches. Invariant under bus renumbering, sensitive to a lost or added branch.

impedances: Vec<i64>

Sorted quantized |z| of every branch.

hvdc: usize

Number of DC lines. A case with an HVDC link is a different case from the AC network underneath it, however alike the two look.

load_p: i64

load_q: i64

Implementations

impl Fingerprint

pub fn of(net: &BalancedNetwork) -> Self

pub fn of_distribution(net: &MulticonductorNetwork) -> Self

A multiconductor network’s fingerprint.

Coarser than the balanced one: a distribution line carries an impedance matrix rather than a scalar, so there is no |z| multiset to compare, and the degree sequence runs over lines, switches and transformers together because formats disagree about which of the three a given device is.

pub fn primary(&self) -> PrimaryKey

The coarse bucketing key: the part of the fingerprint that is exact even across a lossy text format. Sorting by it gives the bucket ordinals, so a bucket id derives from electrical content and from nothing in the source.

pub fn agrees_with(&self, other: &Self) -> bool

Whether two fingerprints sharing a PrimaryKey really are the same case.

Compared with a tolerance rather than by quantized equality: two siblings whose impedance lands either side of a quantum boundary are still the same case, and exact equality on a rounded value would split them. The quantized fields exist to make the fingerprint serializable and sortable; agreement is decided here.
