Enum SvdLibError 

pub enum SvdLibError {
    InvalidArgument(String),
    ShapeMismatch(String),
    NoConvergence {
        stage: &'static str,
        iterations: usize,
    },
    Failed {
        stage: &'static str,
        message: String,
    },
    DenseFactorization {
        factorization: &'static str,
        message: String,
    },
    Shape(String),
}

Everything this crate can fail with.

In 1.x the Lanczos path returned SvdLibError while the randomized path returned anyhow::Error; both now return this type.

Variants

InvalidArgument(String)

A caller-supplied parameter was rejected before any work started.

ShapeMismatch(String)

The operands’ shapes are inconsistent.

NoConvergence

A tridiagonal/bidiagonal eigenproblem failed to converge.

stage names the kernel (imtqlb, imtql2, …) so the origin stays visible without a separate variant per call site.

Fields

stage: &'static str

iterations: usize

Failed

The algorithm ran but could not produce the requested number of dimensions.

Fields

stage: &'static str

message: String

DenseFactorization

A dense factorization from the linear-algebra backend failed.

Fields

factorization: &'static str

message: String

Shape(String)

Trait Implementations

impl Clone for SvdLibError

fn clone(&self) -> SvdLibError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SvdLibError

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

Formats the value using the given formatter.

impl Display for SvdLibError

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

Formats the value using the given formatter.

impl Error for SvdLibError

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 From<ShapeError> for SvdLibError

fn from(e: ShapeError) -> Self

Converts to this type from the input type.

impl PartialEq for SvdLibError

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

Equality operator ==.

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

Inequality operator !=.
