Enum SimplexError 

pub enum SimplexError {
    IndexOutOfBounds {
        index: usize,
        len: usize,
    },
    NotYetSolved,
    Infeasible,
    Unbounded,
}

Error type for SimplexSolver.

Variants

IndexOutOfBounds

Index out of bounds.

Fields

index: usize

The requested index.

len: usize

The length of the collection.

NotYetSolved

Shadow price queried before solving.

Infeasible

The LP is infeasible so shadow prices are undefined.

Unbounded

The LP is unbounded so shadow prices are undefined.

Trait Implementations

impl Clone for SimplexError

fn clone(&self) -> SimplexError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SimplexError

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

Formats the value using the given formatter.

impl Display for SimplexError

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

Formats the value using the given formatter.

impl Error for SimplexError

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.
