Enum Sign 

pub enum Sign {
    Neg = -1,
    Pos = 1,
}

Sign.

Variants

Neg = -1

Negative.

Pos = 1

Positive.

Implementations

impl Sign

pub fn invert(&self) -> Self

Changes the sign to the opposite.

pub fn is_positive(&self) -> bool

Returns true if self is positive.

pub fn is_negative(&self) -> bool

Returns true if self is negative.

pub fn to_int(&self) -> i8

Returns 1 for the positive sign and -1 for the negative sign.

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 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 PartialEq for Sign

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