Struct ProofRule 

pub struct ProofRule {
    pub name: String,
    pub premises: Vec<Node>,
    pub conclusion: Node,
}

A declared rule of inference. Premises and the conclusion are stored as AST nodes; leaves whose token starts with ? are metavariables that bind during check_proof_object. Repeated metavariables must structurally match.

Fields

name: String

premises: Vec<Node>

conclusion: Node

Trait Implementations

impl Clone for ProofRule

fn clone(&self) -> ProofRule

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for ProofRule

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

Formats the value using the given formatter.

impl PartialEq for ProofRule

fn eq(&self, other: &ProofRule) -> 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.
