Enum SolverError 

pub enum SolverError {
    Singular {
        bad_row: Option<usize>,
    },
    Dimensions(String),
    Cancelled,
    Host(String),
}

Failure returned by a RepairSolver.

Variants

Singular

The selected recovery exponents form a singular (non-invertible) matrix.

Fields

bad_row: Option<usize>

Index into recovery_exponents of the unusable row, when known.

Dimensions(String)

The problem’s dimensions were inconsistent with the solver.

Cancelled

The solve was cancelled cooperatively.

Host(String)

An opaque host-side failure (e.g. a wasm host-fn error code).

Trait Implementations

impl Clone for SolverError

fn clone(&self) -> SolverError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SolverError

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

Formats the value using the given formatter.

impl Display for SolverError

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

Formats the value using the given formatter.

impl Eq for SolverError

impl Error for SolverError

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<SolverError> for Par2Error

fn from(error: SolverError) -> Self

Converts to this type from the input type.

impl PartialEq for SolverError

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

Equality operator ==.

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

Inequality operator !=.
