}

Errors raised by semiring construction and matrix operations.

Variants

ShapeMismatch(String)

Operand shapes are incompatible for the requested operation.

Ragged

A from_rows input had rows of unequal length.

NoStar

Closure is undefined: a diagonal entry’s Kleene star does not converge (either the semiring defines no star, or the series diverges here, as with a negative cycle in min-plus or a directed cycle in counting).

LimitExceeded(String)

An explicit size or iteration limit was exceeded.

DimensionOverflow

A matrix dimension product overflowed usize.

Fields

rows: usize

The requested row count.

cols: usize

The requested column count.

InvalidMatrix

A public matrix value violated data.len() == rows * cols.

Fields

rows: usize

The declared row count.

cols: usize

The declared column count.

expected: usize

The expected row-major entry count.

actual: usize

The actual row-major entry count.

IndexOutOfBounds

An index was out of bounds.

Fields

index: usize

The offending index.

len: usize

The valid length.

Trait Implementations

impl Clone for AlgebraError

fn clone(&self) -> AlgebraError

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for AlgebraError

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

Formats the value using the given formatter.

impl Display for AlgebraError

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

Formats the value using the given formatter.

impl Eq for AlgebraError

impl Error for AlgebraError

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 PartialEq for AlgebraError

fn eq(&self, other: &AlgebraError) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.
