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.

NotSquare

Fields

rows: usize

cols: usize

NotThin

Fields

rows: usize

cols: usize

Matrix rows less than columns

NotPositiveDefinite

Non-positive definite matrix

NonInvertible

Non-invertible matrix

EmptyMatrix

Unexpected empty matrix

WrongColumns

Fields

expected: usize

actual: usize

Wrong number of columns in matrix

WrongRows

Trait Implementations

impl Debug for LinalgError

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

Formats the value using the given formatter.

impl Display for LinalgError

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

Formats the value using the given formatter.

impl Error for LinalgError

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

The lower-level source of this error, if any.

fn backtrace(&self) -> Option<&Backtrace>

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

Returns a stack backtrace, if available, of where this error occurred.

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

impl From<ShapeError> for LinalgError

fn from(source: ShapeError) -> Self

Converts to this type from the input type.
