Trait Implementations

impl Add for ArbitraryInt

type Output = ArbitraryInt

The resulting type after applying the + operator.

fn add(self, rhs: Self) -> Self::Output

Performs the + operation.

impl Clone for ArbitraryInt

fn clone(&self) -> ArbitraryInt

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ArbitraryInt

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

Formats the value using the given formatter.

impl Default for ArbitraryInt

fn default() -> Self

Returns the “default value” for a type.

impl Display for ArbitraryInt

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

Formats the value using the given formatter.

impl Div for ArbitraryInt

type Output = ArbitraryInt

The resulting type after applying the / operator.

fn div(self, rhs: Self) -> Self::Output

Performs the / operation.

impl Mul for ArbitraryInt

type Output = ArbitraryInt

The resulting type after applying the * operator.

fn mul(self, rhs: Self) -> Self::Output

Performs the * operation.

impl Neg for ArbitraryInt

type Output = ArbitraryInt

The resulting type after applying the - operator.

fn neg(self) -> Self::Output

Performs the unary - operation.

impl PartialEq for ArbitraryInt

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

type Output = ArbitraryInt

The resulting type after applying the - operator.

fn sub(self, rhs: Self) -> Self::Output

Performs the - operation.

impl Eq for ArbitraryInt
