Struct PredicateDescriptor 

pub struct PredicateDescriptor { /* private fields */ }

A validated static name that converts to the canonical predicate contract.

Descriptors deliberately do not implement Serde. Persisted definitions continue to use the existing { "namespace", "name" } KnowledgePredicate representation.

Implementations

impl PredicateDescriptor

pub const fn namespace(self) -> &'static str

Returns the predicate namespace.

pub const fn name(self) -> &'static str

Returns the predicate name within its namespace.

pub const fn dotted(self) -> &'static str

Returns the stable dotted identifier used in diagnostics.

pub fn into_knowledge(self) -> KnowledgePredicate

Converts this descriptor to the canonical owned predicate type.

Trait Implementations

impl Clone for PredicateDescriptor

fn clone(&self) -> PredicateDescriptor

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Copy for PredicateDescriptor

impl Debug for PredicateDescriptor

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

Formats the value using the given formatter.

impl Eq for PredicateDescriptor

impl From<PredicateDescriptor> for KnowledgePredicate

fn from(value: PredicateDescriptor) -> Self

Converts to this type from the input type.

impl Hash for PredicateDescriptor

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 Ord for PredicateDescriptor

fn cmp(&self, other: &PredicateDescriptor) -> Ordering

This method returns an Ordering between self and other.

fn max(self, other: Self) -> Self

where Self: Sized,

Compares and returns the maximum of two values.

fn min(self, other: Self) -> Self

where Self: Sized,

Compares and returns the minimum of two values.

fn clamp(self, min: Self, max: Self) -> Self

where Self: Sized,

Restrict a value to a certain interval.

impl PartialEq for PredicateDescriptor

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

Equality operator ==.

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

Inequality operator !=.

impl PartialOrd for PredicateDescriptor

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

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

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

Tests less than (for self and other) and is used by the < operator.

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

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

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

Tests greater than (for self and other) and is used by the > operator.

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

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