Errors that can occur during calibration.

#[non_exhaustive] for SemVer-minor variant additions.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

CsvParse

A CSV row had the wrong number of columns, unparseable numeric values or an unknown header layout. line is 1-indexed.

Fields

line: usize

reason: String

TimestampParse

An ISO 8601 timestamp column could not be parsed. Covers missing Z suffix, non-UTC offsets and out-of-range date/time fields.

Fields

line: usize

value: String

reason: String

EmptyData

The CSV parsed successfully but contained zero data rows. At least one measurement is required to compute a calibration.

Io(Error)

Underlying filesystem I/O error when reading the CSV or writing the calibration TOML output.

TomlParse(Error)

The calibration TOML file loaded via [green] calibration_file failed TOML deserialization (malformed syntax, wrong types).

Validation(String)

A semantic validation check failed on an otherwise well-formed calibration TOML: negative or non-finite factor, missing base energy or a service factor outside the accepted range.

Trait Implementations

impl Debug for CalibrationError

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

Formats the value using the given formatter.

impl Display for CalibrationError

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

Formats the value using the given formatter.

impl Error for CalibrationError

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 CalibrationError

fn from(source: Error) -> Self

Converts to this type from the input type.

impl From<Error> for CalibrationError

fn from(source: Error) -> Self
