Comprehensive mathematical error type

Represents all possible error conditions that can occur during mathematical operations, including domain violations, singularities, and undefined behavior.

Variants

DomainError

Domain error - operation not valid for given input

Examples

• sqrt(-1) in real domain
• arcsin(2) in real domain (domain is [-1, 1])

Fields

operation: String

value: Expression

reason: String

DivisionByZero

Division by zero

Examples

• 1/0
• 0^(-1) = 1/0

Undefined

Undefined expression

Examples

• 0^0 (indeterminate form)
• 0/0 (indeterminate form)

Fields

expression: Expression

reason: String

NumericOverflow

Numeric overflow during computation

Fields

operation: String

NotImplemented

Feature not yet implemented

Fields

feature: String

Pole

Pole singularity - function approaches infinity

Examples

• tan(π/2)
• log(0)
• 1/0

Fields

function: String

at: Expression

BranchCut

Branch cut issue for multi-valued functions

Examples

• log(-1) in real domain (requires complex domain)
• sqrt(-1) in real domain (branch cut on negative real axis)

Fields

function: String

value: Expression

InvalidInterval

Invalid integration interval

Examples

• Integration where lower bound >= upper bound

Fields

lower: f64

upper: f64

MaxIterationsReached

Maximum iterations reached without convergence

Fields

max_iterations: usize

ConvergenceFailed

Convergence failure in iterative method

Fields

reason: String

NonNumericalResult

Non-numerical result from evaluation

Examples

• Attempting to convert symbolic expression to f64
• Evaluation resulted in non-numeric expression

Fields

expression: Expression

Trait Implementations

impl Clone for MathError

fn clone(&self) -> MathError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MathError

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

Formats the value using the given formatter.

impl Display for MathError

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

Formats the value using the given formatter.

impl Error for MathError

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 MathError

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