Enum Sign

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

Enumeration over possible signs.

Variants

Pos = 0

Positive.

Neg = 1

Negative.

Implementations

impl Sign

pub const fn iter() -> SignIndexableIter

Returns an iterator over all items of Sign

pub const fn count() -> usize

Returns the number of items that will be returned by SignIndexableIter that are not disabled members of Sign

impl Sign

pub const fn as_int(&self) -> i64

Converts this sign to +1 (if positive) or -1 (if negative).

pub const fn is_pos(&self) -> bool

Returns true if the sign is positive.

pub const fn is_neg(&self) -> bool

Returns true if the sign is negative.

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<(), Error>

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Sign

fn deserialize<__D>( __deserializer: __D, ) -> Result<Sign, <__D as Deserializer<'de>>::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Hash for Sign

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

where __H: Hasher,

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 Indexable for Sign

const SIZE: usize = 2usize

The number of items or variants that this type can have.

const SET_SIZE: usize = 1usize

The number of bytes it will take to represent this type in a set.

type Iter = SignIndexableIter

The type of Iterator that will be returned by [Self::iter()]

fn index(self) -> usize

Maps self to usize to know which value in the underling array to use

fn iter() -> <Sign as Indexable>::Iter

An Iterator over all valid values of self

impl Not for Sign

fn not(self) -> <Sign as Not>::Output

Flips the Sign.

type Output = Sign

The resulting type after applying the ! operator.

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 ReverseIndexable for Sign

fn from_index(u: usize) -> Sign

Converts from a usize to Self

impl Serialize for Sign

fn serialize<__S>( &self, __serializer: __S, ) -> Result<<__S as Serializer>::Ok, <__S as Serializer>::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Copy for Sign

impl Eq for Sign
