Trait Implementations

impl Clone for ModusClause

fn clone(&self) -> ModusClause

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ModusClause

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

Formats the value using the given formatter.

impl Display for ModusClause

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

Formats the value using the given formatter.

impl From<&ModusClause> for Vec<Clause>

fn from(modus_clause: &ModusClause) -> Self

Convert a ModusClause into one supported by the IR. It converts logical or/; into multiple rules, which should be equivalent.

impl FromStr for ModusClause

type Err = String

The associated error which can be returned from parsing.

fn from_str(s: &str) -> Result<Self, Self::Err>

Parses a string s to return a value of this type.

impl PartialEq for ModusClause

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