Struct DetectorErrorModel 

pub struct DetectorErrorModel { /* private fields */ }

Detector error model: independent error mechanisms over a program’s detectors and observables.

Derived by QecProgram::detector_error_model. Mechanisms are ordered by the program position of the noise annotation that first produced each symptom. Detector coordinates are carried verbatim from the program’s detector ops, one entry per detector, empty when the op carried none.

Implementations

impl DetectorErrorModel

pub fn mechanisms(&self) -> &[ErrorMechanism]

pub fn num_mechanisms(&self) -> usize

pub fn num_detectors(&self) -> usize

pub fn num_observables(&self) -> usize

pub fn detector_coords(&self) -> &[Vec<f64>]

Coordinates per detector, in detector order. Empty for detectors whose op carried no coordinates.

pub fn decompose_graphlike(&self) -> Result<DetectorErrorModel>

Decompose hypergraph mechanisms into graphlike components.

Returns a model in which every mechanism flips at most two detectors. A mechanism with more is replaced by existing graphlike mechanisms whose non-empty detector sets partition its detectors and whose observable XOR matches; its probability composes into every component as p = p1(1-p2) + p2(1-p1). Cross-component correlations are lost; single-detector marginals are unchanged. Deterministic: retained mechanisms keep their order, the first cover in mechanism order wins.

Errors

A hypergraph mechanism with no cover; the error names its symptom.

pub fn to_text(&self) -> String

Render the model in the common detector error model text format.

One error(p) D.. L.. line per mechanism in mechanism order, then one detector line per detector (with its coordinates when present), then one logical_observable line per observable slot. The grammar is documented in docs/architecture/qec-programs.md.
