Struct arithmetic_eval::arith::WrappingArithmetic

pub struct WrappingArithmetic;

Arithmetic on an integer type (e.g., i32), in which all operations have wrapping semantics.

As an example, this type implements Arithmetic for all built-in integer types with a definite size (u8, i8, u16, i16, u32, i32, u64, i64, u128, i128).

Trait Implementations

impl<T> Arithmetic<T> for WrappingArithmetic

where T: Copy + PartialEq + Zero + One + WrappingAdd + WrappingSub + WrappingMul + WrappingNeg + Div<T, Output = T>, usize: TryFrom<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 WrappingArithmetic

fn clone(&self) -> WrappingArithmetic

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for WrappingArithmetic

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

Formats the value using the given formatter.

impl Default for WrappingArithmetic

fn default() -> WrappingArithmetic

Returns the “default value” for a type.

impl<T> OrdArithmetic<T> for WrappingArithmetic

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.
