Enum ESymSolverStatus 

pub enum ESymSolverStatus {
    Success,
    Singular,
    WrongInertia,
    CallAgain,
    FatalError,
}

Outcome of a single call into a crate::SymLinearSolver or crate::SparseSymLinearSolverInterface.

Variant order and semantics match upstream Ipopt’s enum ESymSolverStatus so the algorithm-side state machines port 1:1.

Variants

Success

Successful solve. Mirrors SYMSOLVER_SUCCESS.

Singular

Matrix is singular; solve was aborted. Mirrors SYMSOLVER_SINGULAR.

WrongInertia

Inertia mismatch — numberOfNegEVals did not match. Mirrors SYMSOLVER_WRONG_INERTIA.

CallAgain

Backend asks the caller to refill the values array and call again with the same RHS (e.g. MA57 after growing factor arrays). Mirrors SYMSOLVER_CALL_AGAIN.

FatalError

Unrecoverable error — the optimization should abort. Mirrors SYMSOLVER_FATAL_ERROR.

Trait Implementations

impl Clone for ESymSolverStatus

fn clone(&self) -> ESymSolverStatus

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for ESymSolverStatus

impl Debug for ESymSolverStatus

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

Formats the value using the given formatter.

impl Eq for ESymSolverStatus

impl Hash for ESymSolverStatus

fn hash<__H: Hasher>(&self, state: &mut __H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ESymSolverStatus

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

Tests for self and other values to be equal, and is used by ==.

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

Tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
