Enum IntegrationError 

pub enum IntegrationError {
    NotImplemented(String),
    DivisionByZero,
    UnsupportedExtensionDegree(u32),
    NonElementary(String),
}

Variants

NotImplemented(String)

The expression is outside the supported Risch subset.

DivisionByZero

Division by zero would occur (e.g. power-rule with n=-1 on a non-x base).

UnsupportedExtensionDegree(u32)

The algebraic extension has degree > 2 (v1.1 supports only sqrt / degree-2).

NonElementary(String)

The integrand provably has no elementary antiderivative (e.g. elliptic integrals).

Implementations

impl IntegrationError

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

A human-readable remediation hint for the user.

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

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

Trait Implementations

impl AlkahestError for IntegrationError

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 IntegrationError

fn clone(&self) -> IntegrationError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for IntegrationError

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

Formats the value using the given formatter.

impl Display for IntegrationError

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

Formats the value using the given formatter.

impl Error for IntegrationError

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 IntegrationError

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