Custom error type for DataMatrix operations.

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.

IncorrectMatrixLabels

Row or column labels count does not match number of rows / columns

Fields

expected: usize

actual: usize

NotEnoughColumns

Line does not have enough columns.

Fields

line: usize

needed: usize

content: String

TooManyColumns

More than one column found when expecting single column input.

Fields

line: usize

content: String

ParseError

Parsing error at a line.

Fields

line: usize

content: String

WrongNumberOfData

Incorrect number of data values; expected a square matrix packed row-wise.

Fields

n_data: usize

IoError(Error)

Generic I/O error.

Trait Implementations

impl Debug for Error

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

Formats the value using the given formatter.

impl Display for Error

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

Formats the value using the given formatter.

impl Error for Error

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 Error

fn from(source: Error) -> Self

Converts to this type from the input type.
