Enum Sign 

#[repr(i8)]
pub(crate) enum Sign {
    Zero = 0,
    Positive = 1,
    Negative = -1,
}

A representation of a numeric sign.

Its Display impl emits the ASCII minus sign, - when this is negative. It emits the empty string in all other cases.

Variants

Zero = 0

Positive = 1

Negative = -1

Implementations

impl Sign

pub(crate) fn is_negative(&self) -> bool

pub(crate) fn as_ranged_integer(&self) -> ri8<-1, 1>

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() -> Sign

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 Ord for Sign

fn cmp(&self, other: &Sign) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

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.

impl PartialOrd for Sign

fn partial_cmp(&self, other: &Sign) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

fn lt(&self, other: &Rhs) -> bool

Tests less than (for self and other) and is used by the < operator.

fn le(&self, other: &Rhs) -> bool

Tests less than or equal to (for self and other) and is used by the <= operator.

fn gt(&self, other: &Rhs) -> bool

Tests greater than (for self and other) and is used by the > operator.

fn ge(&self, other: &Rhs) -> bool

Tests greater than or equal to (for self and other) and is used by the >= operator.
