Implementations

impl NumberSign

pub fn to_i8(&self) -> i8

Returns a signed 8-bit number representing the sign

• 0 if the number is zero
• 1 if the number is positive
• -1 if the number is negative

use entity::NumberSign;

assert_eq!(NumberSign::Zero.to_i8(), 0);
assert_eq!(NumberSign::Positive.to_i8(), 1);
assert_eq!(NumberSign::Negative.to_i8(), -1);

Trait Implementations

impl Clone for NumberSign

fn clone(&self) -> NumberSign

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NumberSign

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

Formats the value using the given formatter.

impl PartialEq for NumberSign

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