Enum arithmetic_eval::error::ArithmeticError

#[non_exhaustive]
pub enum ArithmeticError {
    IntegerOverflow,
    DivisionByZero,
    InvalidExponent,
    NoInverse,
    InvalidOp(Error),
}

Arithmetic errors raised by Arithmetic operations on primitive values.

Variants (Non-exhaustive)

Non-exhaustive enums could have additional variants added in future. Therefore, when matching against variants of non-exhaustive enums, an extra wildcard arm must be added to account for any future variants.

IntegerOverflow

Integer overflow or underflow.

DivisionByZero

Division by zero.

InvalidExponent

Exponent of Arithmetic::pow() cannot be converted to usize, for example because it is too large or negative.

NoInverse

Integer used as a denominator in Arithmetic::div() has no multiplicative inverse.

InvalidOp(Error)

Invalid operation with a custom error message.

This error may be used by Arithmetic implementations as a catch-all fallback.

Implementations

impl ArithmeticError

pub fn invalid_op(message: impl Into<String>) -> Self

Creates a new invalid operation error with the specified message.

Trait Implementations

impl Debug for ArithmeticError

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

Formats the value using the given formatter.

impl Display for ArithmeticError

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

Formats the value using the given formatter.

impl Error for ArithmeticError

fn source(&self) -> Option<&(dyn Error + 'static)>

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.
