Enum DsolveSystemError 

pub enum DsolveSystemError {
    NotLinear(String),
    NonConstantCoefficient(String),
    UnsupportedSpectrum(String),
    Unsupported(String),
    VerificationFailed(String),
}

Errors / declines from dsolve_system.

Variants

NotLinear(String)

A right-hand side is not affine in the state variables.

NonConstantCoefficient(String)

A coefficient of the state depends on the independent variable, so the system is y' = A(t)·y and e^{At} is not its fundamental matrix.

UnsupportedSpectrum(String)

The eigenvalues of A are not available in closed form.

Unsupported(String)

The forcing term could not be closed (a required integral is not elementary), or some other step declined.

VerificationFailed(String)

A candidate was produced and failed the substitution gate, so it is withheld rather than returned.

Trait Implementations

impl Clone for DsolveSystemError

fn clone(&self) -> Self

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DsolveSystemError

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

Formats the value using the given formatter.

impl Display for DsolveSystemError

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

impl Eq for DsolveSystemError

impl Error for DsolveSystemError

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 DsolveSystemError

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

Equality operator ==.
