Enum DenseError 

pub enum DenseError {
    NotPositiveDefinite {
        position: usize,
    },
    Dimension,
}

Error raised by a crate::DenseKernel (Chapter 5.16).

Variants

NotPositiveDefinite

The block is not positive definite: the pivot of column position is not positive (or not finite).

Fields

position: usize

Column whose pivot failed.

Dimension

The dimensions of the blocks do not agree (or a block that must be square is not).

Trait Implementations

impl Clone for DenseError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DenseError

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

Formats the value using the given formatter.

impl Display for DenseError

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

Formats the value using the given formatter.

impl Eq for DenseError

impl Error for DenseError

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 DenseError

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

Equality operator ==.

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

Inequality operator !=.
