Enum Boolean

pub enum Boolean {
    False,
    True,
}

True

Implementations

impl Boolean

pub fn new(value: bool) -> Self

Creates a Boolean based on the given primitive bool. If the value is true, it will return Boolean::True and if the value isfalse will return Boolean::False

pub fn and<R: Into<Self>>(self, rhs: R) -> Self

The logical and operation.

Truth table:

self	rhs	output
True	True	True
True	False	False
False	True	False
False	False	False

pub fn or<R: Into<Self>>(self, rhs: R) -> Self

The logical or operation.

Truth table:

self	rhs	output
True	True	True
True	False	True
False	True	True
False	False	False

pub fn not(self) -> Self

The logical not operation.

Truth table:

self	output
True	False
False	True

pub fn implication<R: Into<Self>>(self, rhs: R) -> Self

The logical [implication] operation.

Truth table:

self	rhs	output
True	True	True
True	False	False
False	True	True
False	False	True

pub fn xor<R: Into<Self>>(self, rhs: R) -> Self

The logical xor operation.

Truth table:

self	rhs	output
True	True	False
True	False	True
False	True	True
False	False	False

pub fn equivalence<R: Into<Self>>(self, rhs: R) -> Self

The logical equivalence operation.

Truth table:

self	rhs	output
True	True	True
True	False	False
False	True	False
False	False	True

pub fn is_true(self) -> bool

pub fn then<T>(self, f: impl FnOnce() -> T) -> Option<T>

Trait Implementations

impl BitAnd for Boolean

type Output = Boolean

The resulting type after applying the & operator.

fn bitand(self, rhs: Self) -> Self::Output

Performs the & operation.

impl BitAndAssign for Boolean

fn bitand_assign(&mut self, rhs: Self)

Performs the &= operation.

impl BitOr for Boolean

type Output = Boolean

The resulting type after applying the | operator.

fn bitor(self, rhs: Self) -> Self::Output

Performs the | operation.

impl BitOrAssign for Boolean

fn bitor_assign(&mut self, rhs: Self)

Performs the |= operation.

impl BitXor for Boolean

type Output = Boolean

The resulting type after applying the ^ operator.

fn bitxor(self, rhs: Self) -> Self::Output

Performs the ^ operation.

impl BitXorAssign for Boolean

fn bitxor_assign(&mut self, rhs: Self)

Performs the ^= operation.

impl Clone for Boolean

fn clone(&self) -> Boolean

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Boolean

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

Formats the value using the given formatter.

impl Default for Boolean

The default for Boolean is False.

fn default() -> Self

Returns the “default value” for a type.

impl From<&Boolean> for bool

fn from(item: &Boolean) -> Self

Converts to this type from the input type.

impl From<&mut Boolean> for bool

fn from(item: &mut Boolean) -> Self

Converts to this type from the input type.

impl From<Boolean> for bool

fn from(item: Boolean) -> Self

Converts to this type from the input type.

impl From<bool> for Boolean

fn from(item: bool) -> Self

Converts to this type from the input type.

impl FromStr for Boolean

fn from_str(s: &str) -> Result<Self, Self::Err>

Important: if the crate has the alloc crate is available and the ‘has_alloc’ feature is enabled, it allows for a “true” or “false” value with any casing (e.g. “True” or “trUE” are equivalent to “true”). If the feature ‘has_alloc’ is set to false, only the values “true”, “True”, “TRUE”, “false”, “False” and “FALSE” will be accepted as valid inputs.

type Err = BooleanError

The associated error which can be returned from parsing.

impl Not for Boolean

type Output = Boolean

The resulting type after applying the ! operator.

fn not(self) -> Self::Output

Performs the unary ! operation.

impl Ord for Boolean

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

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

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

impl Copy for Boolean
