Enum BoundsError 

#[non_exhaustive]
pub enum BoundsError {
    Empty,
    DimMismatch {
        dim: usize,
        bounds: usize,
    },
    NotOrdered {
        dim: usize,
        lo: f64,

}

Why a problem’s bounds are invalid.

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.

Empty

No decision variables were given.

DimMismatch

bounds().len() disagrees with dim().

Fields

dim: usize

What dim() reported.

bounds: usize

How many bound pairs bounds() returned.

NotOrdered

Dimension dim has lower >= upper (or a NaN bound).

Fields

dim: usize

Index of the offending variable.

lo: f64

Its lower bound.

hi: f64

Its upper bound.

BadObjectiveCount

objectives() length disagrees with n_objectives() (or fewer than 2).

Fields

declared: usize

What n_objectives() declared.

got: usize

What objectives() actually returned.

Trait Implementations

impl Clone for BoundsError

fn clone(&self) -> BoundsError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for BoundsError

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

Formats the value using the given formatter.

impl Display for BoundsError

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

Formats the value using the given formatter.

impl Error for BoundsError

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 BoundsError

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

Equality operator ==.

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

Inequality operator !=.
