Struct Predicate 

pub struct Predicate {
    pub name: String,
    pub terms: Vec<Term>,
}

Builder for a Datalog predicate, used in facts and rules

Fields

name: String

terms: Vec<Term>

Implementations

impl Predicate

pub fn new<T: Into<Vec<Term>>>(name: String, terms: T) -> Predicate

Trait Implementations

impl AsRef<Predicate> for Predicate

fn as_ref(&self) -> &Predicate

Converts this type into a shared reference of the (usually inferred) input type.

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 Convert<Predicate> for Predicate

fn convert(&self, symbols: &mut SymbolTable) -> Predicate

fn convert_from(p: &Predicate, symbols: &SymbolTable) -> Result<Self, Format>

fn translate( f: &T, from_symbols: &SymbolTable, to_symbols: &mut SymbolTable, ) -> Result<T, Format>

impl Debug for Predicate

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

Formats the value using the given formatter.

impl Display for Predicate

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

Formats the value using the given formatter.

impl From<Predicate> for Predicate

fn from(p: Predicate) -> Self

Converts to this type from the input type.

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.
