Enum Literal

pub enum Literal {
    Pos(Rc<String>),
    Neg(Rc<String>),
}

A positive or negated variable identified by its name.

Cloning is efficient because the name is shared.

Variants

Pos(Rc<String>)

Neg(Rc<String>)

Implementations

impl Literal

pub fn var(&self) -> &str

Returns the name of the variable.

pub fn is_negated(&self) -> bool

Returns true if the literal is negated, false otherwise.

Trait Implementations

impl Clone for Literal

fn clone(&self) -> Literal

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Literal

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

Formats the value using the given formatter.

impl Display for Literal

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

Formats the value using the given formatter.

impl From<&Literal> for Gate

fn from(literal: &Literal) -> Gate

Converts a literal to either a variable or a gate that is the negation of a variable.

impl From<&str> for Literal

fn from(name: &str) -> Literal

Converts to this type from the input type.

impl Hash for Literal

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 Not for &Literal

type Output = Literal

The resulting type after applying the ! operator.

fn not(self) -> Literal

Performs the unary ! operation.

impl Not for Literal

type Output = Literal

The resulting type after applying the ! operator.

fn not(self) -> Literal

Performs the unary ! operation.

impl PartialEq for Literal

fn eq(&self, other: &Literal) -> 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.
