Enum DiffError 

pub enum DiffError {
    UnknownFunction(String),
    NonIntegerExponent,
    ForwardUnknownFunction(String),
    ForwardNonIntegerExponent,
}

Variants

UnknownFunction(String)

An unknown function was encountered; differentiation is not defined.

NonIntegerExponent

A Pow node whose exponent is not a constant integer.

ForwardUnknownFunction(String)

Forward-mode: unknown function (folded from the former ForwardDiffError).

ForwardNonIntegerExponent

Forward-mode: non-integer exponent (folded from the former ForwardDiffError).

Trait Implementations

impl AlkahestError for DiffError

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 DiffError

fn clone(&self) -> DiffError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for DiffError

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

Formats the value using the given formatter.

impl Display for DiffError

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

Formats the value using the given formatter.

impl Error for DiffError

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 From<DiffError> for CadError

fn from(value: DiffError) -> Self

Converts to this type from the input type.

impl From<DiffError> for LimitError

fn from(e: DiffError) -> Self

Converts to this type from the input type.

impl From<DiffError> for SeriesError

fn from(e: DiffError) -> Self

Converts to this type from the input type.

impl PartialEq for DiffError

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