Enum SolverError Copy item path

Source 
pub enum SolverError {
    Cost(&'static str),
    NotFiniteComputation(&'static str),
    ProjectionFailed(&'static str),
    LinearAlgebraFailure(&'static str),
    InvalidProblemState(&'static str),
}
Expand description

Exceptions/errors that may arise while solving a problem.

In the Rust API, numerical failures are generally reported through Result<_, SolverError>:

By contrast, blatant API misuse such as inconsistent slice dimensions may still panic in some low-level routines.

Variants

Cost(&'static str)

If the gradient or cost function cannot be evaluated

NotFiniteComputation(&'static str)

Computation failed and NaN/Infinite value was obtained

ProjectionFailed(&'static str)

A projection could not be computed numerically

LinearAlgebraFailure(&'static str)

A linear algebra operation failed

InvalidProblemState(&'static str)

The solver reached an unexpected internal state
