Enum Sign 

#[repr(u8)]
pub enum Sign {
    Plus = 0,
    Minus = 1,
}

A Sign represents sign associated with a decimal number.

Variants

Plus = 0

Positive: plus “+” or no sign.

Minus = 1

Negative: minus “-” sign.

Implementations

impl Sign

pub const fn default() -> Self

Returns the default Plus.

pub const fn is_negative(self) -> bool

Returns true if sign is negative, and false otherwise.

pub const fn eq(&self, other: &Self) -> bool

Tests for self and other signs to be equal, and is used by == operator.

pub const fn not(self) -> Self

Invert Sign value.

Example

use fastnum::decimal::Sign;

assert_eq!(Sign::Plus.not(), Sign::Minus);
assert_eq!(Sign::Minus.not(), Sign::Plus);

pub const fn mul(self, rhs: Self) -> Self

Sign “multiplication”.

pub const fn div(self, rhs: Self) -> Self

Sign “division”.

Trait Implementations

impl Clone for Sign

fn clone(&self) -> Sign

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Sign

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

Formats the value using the given formatter.

impl Default for Sign

fn default() -> Self

Returns the “default value” for a type.

impl Display for Sign

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

Formats the value using the given formatter.

impl Hash for Sign

fn hash<H: Hasher>(&self, state: &mut H)

Feeds this value into the given Hasher.

fn hash_slice<H>(data: &[Self], state: &mut H)

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl Mul for Sign

type Output = Sign

The resulting type after applying the * operator.

fn mul(self, other: Sign) -> Sign

Performs the * operation.

impl Not for Sign

type Output = Sign

The resulting type after applying the ! operator.

fn not(self) -> Self::Output

Performs the unary ! operation.

impl PartialEq for Sign

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