Trait Implementations

impl Clone for ArithmeticOperator

fn clone(&self) -> ArithmeticOperator

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ArithmeticOperator

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

Formats the value using the given formatter.

impl Display for ArithmeticOperator

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

Formats the value using the given formatter.

impl FromStr for ArithmeticOperator

type Err = ParseError

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<ArithmeticOperator, <Self as FromStr>::Err>

Parses a string s to return a value of this type.

impl PartialEq for ArithmeticOperator

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

impl TryFrom<&str> for ArithmeticOperator

type Error = ParseError

The type returned in the event of a conversion error.

fn try_from( s: &str, ) -> Result<ArithmeticOperator, <Self as TryFrom<&str>>::Error>

Performs the conversion.

impl Copy for ArithmeticOperator

impl Eq for ArithmeticOperator
