Why a coefficient or a sign is not given.

Variants

NotComputed

The flow’s update matrices do not commute, so its coefficients past the standard part are not computed exactly. The order is the exponent of dt.

Fields

order: Rational

StandardOnly

The value is known by its standard part alone, as a nonlinear flow is. The order is the exponent of dt.

Fields

order: Rational

Inseparable(String)

A coefficient could not be told from zero.

Flat

The coefficients through dt^SIGN_ORDERS vanish.

DivisionByZero

The reciprocal of a germ that may be zero.

NegativeRoot(u32)

An even root of a negative value.

Nonpositive

The logarithm of a negative value.

BeyondEveryPower

The exponential of an infinite value, beyond every power of dt.

CarriesLog

The logarithm of a positive infinitesimal, which carries ln(dt), or of an infinite value, which carries ln(1/dt).

Fields

infinite: bool

Trait Implementations

impl Clone for GermError

fn clone(&self) -> GermError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for GermError

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

Formats the value using the given formatter.

impl Display for GermError

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

Formats the value using the given formatter.

impl From<RealError> for GermError

fn from(e: RealError) -> GermError

Converts to this type from the input type.

impl PartialEq for GermError

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