Errors produced by the detections pipeline (load/validate/filter/resolve).

ConflictingDetections and UnknownNetelement are FATAL per data-model.md and abort path calculation. All other variants surface either as parse-time failures or as recoverable DiscardReasons in DetectionRecord.

Variants

UnsupportedExtension(String)

Input file extension is not .csv, .geojson, or .json.

InvalidSchema(String)

Required column / property missing or malformed schema.

Parse

Generic parser failure (CSV row, GeoJSON feature).

Fields

source_file: String

source_row: usize

message: String

InvalidTimestamp

Timestamp could not be parsed or lacked a timezone offset.

Fields

source_file: String

source_row: usize

message: String

InvalidIntrinsic

intrinsic / start_intrinsic / end_intrinsic not in [0, 1].

Fields

source_file: String

source_row: usize

value: f64

MissingCrs

Coordinate row supplied without a crs column / property.

Fields

source_file: String

source_row: usize

ConflictingDetections

Two punctual detections at the same timestamp resolve to different netelements (FATAL, D4).

Fields

timestamp: DateTime<FixedOffset>

netelement_a: String

netelement_b: String

InvalidTimeRange

Linear detection has t_from > t_to.

Fields

source_file: String

source_row: usize

t_from: DateTime<FixedOffset>

t_to: DateTime<FixedOffset>

UnknownNetelement

netelement_id does not exist in the supplied railway network (FATAL, FR-006).

Fields

source_file: String

source_row: usize

netelement_id: String

DuplicateResolution

Internal invariant violation: a detection resolved twice.

Fields

source_file: String

source_row: usize

Io(Error)

Wrapped std::io::Error.

Trait Implementations

impl Debug for DetectionError

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Display for DetectionError

fn fmt(&self, __formatter: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Error for DetectionError

fn source(&self) -> Option<&(dyn Error + 'static)>

Returns the lower-level source of this error, if any.

fn description(&self) -> &str

👎Deprecated since 1.42.0:

use the Display impl or to_string()

fn cause(&self) -> Option<&dyn Error>

👎Deprecated since 1.33.0:

replaced by Error::source, which can support downcasting

fn provide<'a>(&'a self, request: &mut Request<'a>)

🔬This is a nightly-only experimental API. (error_generic_member_access)

Provides type-based access to context intended for error reports.

impl From<Error> for DetectionError

fn from(source: Error) -> Self

Converts to this type from the input type.
