Enum fraction::Sign

pub enum Sign {
    Plus,
    Minus,
}

Sign representation

Fractions keep the sign represented by this enum, so that we can use unsigned ints as base data types.

Variants

Plus

Minus

Implementations

impl Sign

pub fn is_positive(self) -> bool

pub fn is_negative(self) -> bool

Trait Implementations

impl Clone for Sign

fn clone(&self) -> Sign

Returns a copy 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 Display for Sign

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

Formats the value using the given formatter.

impl From<Sign> for char

fn from(sign: Sign) -> char

Converts to this type from the input type.

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, oth: Sign) -> Self::Output

Performs the * operation.

impl Neg for Sign

type Output = Sign

The resulting type after applying the - operator.

fn neg(self) -> Sign

Performs the unary - operation.

impl Ord for Sign

fn cmp(&self, other: &Self) -> 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 + PartialOrd,

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: &Self) -> 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.
