Error produced when constructing a BlockJacobiPrecond.

Variants

NonSquareMatrix

The source matrix was not square.

Fields

nrows: usize

ncols: usize

EmptyBlocks

Less than two offsets were supplied (need at least one block).

BlockOffsetsMustStartAtZero

The first offset must be 0.

Fields

first: usize

BlockOffsetsMustEndAtDim

The last offset must equal the matrix dimension.

Fields

last: usize

dim: usize

BlockOffsetsNotStrictlyIncreasing

Offsets must be strictly increasing — blocks of size 0 are rejected.

Fields

index: usize

prev: usize

curr: usize

SingularBlock

One of the diagonal blocks was singular (numerically rank-deficient).

Fields

block_index: usize

Trait Implementations

impl Clone for BlockJacobiError

fn clone(&self) -> BlockJacobiError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BlockJacobiError

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

Formats the value using the given formatter.

impl Display for BlockJacobiError

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

Formats the value using the given formatter.

impl Eq for BlockJacobiError

impl Error for BlockJacobiError

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 BlockJacobiError

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
