Struct resolution_prover::Clause

pub struct Clause {
    pub parts: Vec<ClausePart>,
}

A proposition made up of the disjunction of possibly negated terms.

For example the proposition p \/ ~q \/ r would be represetnted as the following.

let clause = resolution_prover::Clause {
    parts: vec!(
        resolution_prover::ClausePart::Term("p".to_string()),
        resolution_prover::ClausePart::NegatedTerm("q".to_string()),
        resolution_prover::ClausePart::Term("r".to_string())
    )
};

Fields

parts: Vec<ClausePart>

Methods

impl Clause

pub fn from_proposition(prop: Proposition) -> Vec<Clause>

Converts the given proposition into the corresponding clauses. Note that one proposition could break down into one or more clauses.

let prop1 = resolution_prover::term("hello".to_string());

let expected = vec!(resolution_prover::Clause {
    parts: vec!(
        resolution_prover::ClausePart::Term("hello".to_string())
    )
});

assert_eq!(
    resolution_prover::Clause::from_proposition(prop1),
    expected
);
