Enum Predicate 

pub enum Predicate {
    EqLit(LcnfVarId, LcnfLit),
    NeLit(LcnfVarId, LcnfLit),
    VarEq(LcnfVarId, LcnfVarId),
}

A predicate known to hold at a program point, derived from branch conditions. Used to refine value numbering inside conditional branches.

Variants

EqLit(LcnfVarId, LcnfLit)

Variable equals a literal value.

NeLit(LcnfVarId, LcnfLit)

Variable is not equal to a literal value.

VarEq(LcnfVarId, LcnfVarId)

Two variables are equal.

Trait Implementations

impl Clone for Predicate

fn clone(&self) -> Predicate

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for Predicate

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

Formats the value using the given formatter.

impl Hash for Predicate

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 PartialEq for Predicate

fn eq(&self, other: &Predicate) -> 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 Eq for Predicate
