Struct holmes::engine::types::Fact

pub struct Fact {
    pub pred_name: String,
    pub args: Vec<Value>,
}

A Fact is a particular filling of a Predicate's slots such that it is considered true.

Following the Predicate example,

foo(3, "argblarg")

would be constructed as

use holmes::pg::dyn::values::ToValue;
use holmes::engine::types::Fact;
Fact {
  pred_name : "foo".to_string(),
  args : vec![3.to_value(), "argblarg".to_value()]
};

Fields

pred_name: String

Predicate name

args: Vec<Value>

Slot values which make the predicate true

Trait Implementations

impl PartialEq for Fact

fn eq(&self, __arg_0: &Fact) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, __arg_0: &Fact) -> bool

This method tests for !=.

impl Clone for Fact

fn clone(&self) -> Fact

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Fact

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Hash for Fact

fn hash<__H: Hasher>(&self, __arg_0: &mut __H)

Feeds this value into the given [Hasher].

fn hash_slice<H>(data: &[Self], state: &mut H) where
    H: Hasher, 

Feeds a slice of this type into the given [Hasher].
