Struct arithmetic_eval::arith::StdArithmetic

pub struct StdArithmetic;

Arithmetic on a number type that implements all necessary operations natively.

As an example, this type implements Arithmetic for f32, f64, and the floating-point complex numbers from the num-complex crate.

Trait Implementations

impl<T> Arithmetic<T> for StdArithmetic

where T: Clone + NumOps + PartialEq + Neg<Output = T> + Pow<T, Output = T>,

fn add(&self, x: T, y: T) -> Result<T, ArithmeticError>

Adds two values.

fn sub(&self, x: T, y: T) -> Result<T, ArithmeticError>

Subtracts two values.

fn mul(&self, x: T, y: T) -> Result<T, ArithmeticError>

Multiplies two values.

fn div(&self, x: T, y: T) -> Result<T, ArithmeticError>

Divides two values.

fn pow(&self, x: T, y: T) -> Result<T, ArithmeticError>

Raises x to the power of y.

fn neg(&self, x: T) -> Result<T, ArithmeticError>

Negates a value.

fn eq(&self, x: &T, y: &T) -> bool

Checks if two values are equal. Note that equality can be a non-trivial operation; e.g., different numbers may be equal as per modular arithmetic.

impl Clone for StdArithmetic

fn clone(&self) -> StdArithmetic

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for StdArithmetic

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

Formats the value using the given formatter.

impl Default for StdArithmetic

fn default() -> StdArithmetic

Returns the “default value” for a type.

impl<T> OrdArithmetic<T> for StdArithmetic

where Self: Arithmetic<T>, T: PartialOrd,

fn partial_cmp(&self, x: &T, y: &T) -> Option<Ordering>

Compares two values. Returns None if the numbers are not comparable, or the comparison result otherwise.
