Errors returned by UMFPACK bindings.

Variants

EmptyMatrix

The input matrix has a zero-sized dimension.

NonSquareMatrix

UMFPACK’s direct solver requires a square matrix.

Fields

rows: usize

Number of rows in the matrix.

columns: usize

Number of columns in the matrix.

InvalidCsr(&'static str)

The CSR data does not satisfy the expected storage invariants.

IndexOutOfRange(usize)

A matrix dimension or sparse index cannot be represented by UMFPACK’s 64-bit index type.

DimensionMismatch

A right-hand side or solution has the wrong length.

Fields

expected: usize

Required vector length.

actual: usize

Actual vector length.

NonContiguousArray(&'static str)

An array argument is not contiguous in memory.

DataUnavailable(&'static str)

An array argument does not expose its backing data.

NativeFailure

UMFPACK returned a failure status.

Fields

operation: &'static str

Native operation that failed.

status: i32

UMFPACK status code.

NullHandle(&'static str)

UMFPACK reported success but did not return the expected native handle.

Trait Implementations

impl Clone for UmfpackError

fn clone(&self) -> UmfpackError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for UmfpackError

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

Formats the value using the given formatter.

impl Display for UmfpackError

impl Eq for UmfpackError

impl Error for UmfpackError

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 UmfpackError

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

Equality operator ==.

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

Inequality operator !=.
