Enum DsolveError 

pub enum DsolveError {
    Unsupported(String),
    VerificationFailed(String),
    DiffError(String),
}

Errors / declines from dsolve.

Variants

Unsupported(String)

The ODE did not match any implemented solvable class, or a required quadrature did not close in elementary form.

VerificationFailed(String)

A candidate closed form was produced but failed the substitution verification gate (so it is withheld rather than returned wrong).

DiffError(String)

Differentiation of an intermediate expression failed.

Trait Implementations

impl AlkahestError for DsolveError

fn code(&self) -> &'static str

Stable diagnostic code, e.g. "E-DIFF-001".

fn remediation(&self) -> Option<&'static str>

Optional human-readable fix suggestion.

fn span(&self) -> Option<(usize, usize)>

Optional source span (start_byte, end_byte) within the input text.

impl Clone for DsolveError

fn clone(&self) -> DsolveError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DsolveError

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

Formats the value using the given formatter.

impl Display for DsolveError

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

Formats the value using the given formatter.

impl Eq for DsolveError

impl Error for DsolveError

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 DsolveError

fn eq(&self, other: &DsolveError) -> 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.
