Struct BoolRing 

pub struct BoolRing(pub bool);

The two-element boolean semiring: add is OR, mul is AND.

Tuple Fields

0: bool

Trait Implementations

impl Clone for BoolRing

fn clone(&self) -> BoolRing

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for BoolRing

impl Debug for BoolRing

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

Formats the value using the given formatter.

impl Eq for BoolRing

impl PartialEq for BoolRing

fn eq(&self, other: &BoolRing) -> bool

Equality operator ==.

fn ne(&self, other: &Rhs) -> bool

Inequality operator !=.

impl Semiring for BoolRing

fn star(&self) -> Option<Self>

Reachability closure of a scalar is always reachable: 1 + a + ... = 1.

fn zero() -> Self

The additive identity, also meaning “no value” / “no path”.

fn one() -> Self

The multiplicative identity.

fn add(&self, other: &Self) -> Self

Combine two alternatives.

fn mul(&self, other: &Self) -> Self

Chain two values in sequence.

fn is_zero(&self) -> bool

Whether this value is the additive identity.
