Enum SymmetricEigenError 

#[non_exhaustive]
pub enum SymmetricEigenError {
    Failed,
}

Reasons a SymmetricEigen::try_eigh call can fail. Variants are backend-agnostic — backends translate their native error types into these.

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.

Failed

The eigensolver iteration failed to converge to the requested accuracy. Both backends use bounded-iteration QR / divide-and- conquer methods that can in principle fail on pathological inputs.

Trait Implementations

impl Clone for SymmetricEigenError

fn clone(&self) -> SymmetricEigenError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for SymmetricEigenError

impl Debug for SymmetricEigenError

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

Formats the value using the given formatter.

impl Display for SymmetricEigenError

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

Formats the value using the given formatter.

impl Eq for SymmetricEigenError

impl Error for SymmetricEigenError

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 SymmetricEigenError

fn eq(&self, other: &SymmetricEigenError) -> 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.
