Enum MathOp 

#[non_exhaustive]
pub enum MathOp {
    Add,
    Sub,
    Mul,
    Div,
    Rem,
    Neg,
}

The math operation that caused the error.

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.

Add

Addition failed (core::ops::Add resulted in an invalid value).

Sub

Subtraction failed (core::ops::Sub resulted in an invalid value).

Mul

Multiplication failed (core::ops::Mul resulted in an invalid value).

Div

Division failed (core::ops::Div attempted div-by-zero).

Rem

Calculating the remainder failed (core::ops::Rem attempted div-by-zero).

Neg

Negation failed (core::ops::Neg resulted in an invalid value).

Implementations

Returns true if this operation error’ed due to division by zero.

pub fn is_addition(self) -> bool

Returns true if this operation error’ed due to addition.

pub fn is_subtraction(self) -> bool

Returns true if this operation error’ed due to subtraction.

pub fn is_multiplication(self) -> bool

Returns true if this operation error’ed due to multiplication.

pub fn is_negation(self) -> bool

Returns true if this operation error’ed due to negation.

Trait Implementations

impl<'a> Arbitrary<'a> for MathOp

Available on crate feature arbitrary only.

fn arbitrary(u: &mut Unstructured<'a>) -> Result<Self>

Generate an arbitrary value of Self from the given unstructured data.

fn arbitrary_take_rest(u: Unstructured<'a>) -> Result<Self, Error>

Generate an arbitrary value of Self from the entirety of the given unstructured data.

fn size_hint(depth: usize) -> (usize, Option<usize>)

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

fn try_size_hint( depth: usize, ) -> Result<(usize, Option<usize>), MaxRecursionReached>

Get a size hint for how many bytes out of an Unstructured this type needs to construct itself.

impl Clone for MathOp

fn clone(&self) -> MathOp

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for MathOp

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

Formats the value using the given formatter.

impl Display for MathOp

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

Formats the value using the given formatter.

impl PartialEq for MathOp

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