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.

DimensionMismatch(String)

NonFiniteCoefficient

Non-finite coefficient (NaN or ±∞) in the named field at the given index.

Fields

field: &'static str

index: usize

InvalidBounds

Invalid variable bound: NaN or lb > ub at the given index.

Fields

index: usize

lb: f64

ub: f64

TripletIndexOutOfBounds

A triplet (row, col) index exceeds the matrix dimension.

Fields

constraint: usize

row: usize

col: usize

n: usize

Trait Implementations

impl Debug for QpProblemError

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

Formats the value using the given formatter.

impl Display for QpProblemError

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

Formats the value using the given formatter.

impl Error for QpProblemError

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.
