Struct modus_lib::sld::Proof

pub struct Proof {
    pub clause: ClauseId,
    pub valuation: Substitution,
    pub children: Vec<Proof>,
}

A proof tree consist of

• a clause
• a valuation for this clause
• proofs for parts of the clause body

Fields

clause: ClauseId

valuation: Substitution

children: Vec<Proof>

Trait Implementations

impl Clone for Proof

fn clone(&self) -> Proof

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Proof

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

Formats the value using the given formatter.

impl PartialEq<Proof> for Proof

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

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

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

This method tests for !=.

impl PartialOrd<Proof> for Proof

fn partial_cmp(&self, other: &Self) -> Option<Ordering>

This method returns an ordering between self and other values if one exists.

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

This method tests less than (for self and other) and is used by the < operator.

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

This method tests less than or equal to (for self and other) and is used by the <= operator.

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

This method tests greater than (for self and other) and is used by the > operator.

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

This method tests greater than or equal to (for self and other) and is used by the >= operator.
