Struct polar_core::resource_block::ShorthandRule

pub struct ShorthandRule {
    pub head: Term,
    pub body: (Term, Option<(Term, Term)>),
}

Fields

head: Term

Term is a String. E.g., "member" in "member" if "owner";.

body: (Term, Option<(Term, Term)>)

The first Term is the ‘implier’ String, e.g., "owner" in "member" if "owner";. The Option is the optional ‘relation’ Symbol and String, e.g., on "parent" in "member" if "owner" on "parent";.

Implementations

impl ShorthandRule

pub fn as_rule( &self, resource_name: &Term, blocks: &ResourceBlocks ) -> PolarResult<Rule>

Trait Implementations

impl Clone for ShorthandRule

fn clone(&self) -> ShorthandRule

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for ShorthandRule

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

Formats the value using the given formatter.

impl Hash for ShorthandRule

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

Feeds this value into the given Hasher.

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

where H: Hasher, Self: Sized,

Feeds a slice of this type into the given Hasher.

impl PartialEq for ShorthandRule

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

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

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

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
