Enum SesError 

pub enum SesError {
    UnboundVariable(String),
    MathDomainError(String),
    ParseError(String),
    DivisionByZero,
}

Errors that can occur during symbolic expression operations.

Variants

UnboundVariable(String)

A variable was not found in the provided bindings.

MathDomainError(String)

A numeric operation produced an invalid result (e.g. ln of negative).

ParseError(String)

A parse error with a descriptive message.

DivisionByZero

Division by zero attempted during evaluation.

Trait Implementations

impl Clone for SesError

fn clone(&self) -> SesError

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for SesError

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

Formats the value using the given formatter.

impl Display for SesError

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

Formats the value using the given formatter.

impl Error for SesError

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 SesError

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