Enum TernaryValue 

pub enum TernaryValue {
    Negative = -1,
    Neutral = 0,
    Positive = 1,
}

A ternary value: negative, neutral, or positive.

Variants

Negative = -1

Neutral = 0

Positive = 1

Implementations

impl TernaryValue

pub fn from_i8(v: i8) -> Self

Create from an i8. Clamps to the nearest ternary value.

pub fn as_i8(self) -> i8

Convert to i8.

pub fn flip(self) -> Self

Flip the sign: Negative ↔ Positive, Neutral stays Neutral.

pub fn all() -> [TernaryValue; 3]

Get all three values.

pub fn from_seed(seed: u32) -> Self

Random value given a u32 seed (simple deterministic).

Trait Implementations

impl Clone for TernaryValue

fn clone(&self) -> TernaryValue

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for TernaryValue

impl Debug for TernaryValue

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

Formats the value using the given formatter.

impl Display for TernaryValue

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

Formats the value using the given formatter.

impl Eq for TernaryValue

impl Hash for TernaryValue

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 TernaryValue

fn cmp(&self, other: &TernaryValue) -> 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 TernaryValue

fn eq(&self, other: &TernaryValue) -> 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 TernaryValue

fn partial_cmp(&self, other: &TernaryValue) -> 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.
