Struct FactFingerprint 

pub struct FactFingerprint(/* private fields */);

A deduplication key for “the same fact stated twice”.

A fingerprint is a hint, not an identity: reconciliation may still decide two differently-fingerprinted candidates are semantically equivalent, or that two identically-fingerprinted ones differ by context.

Implementations

impl FactFingerprint

pub fn new( subject: &EntityRef, predicate: &CanonicalPredicate, value: &MemoryValue, scope: TemporalScope, ) -> Self

Build a fingerprint from the normalized triple plus temporal scope.

pub fn as_str(&self) -> &str

Borrow the fingerprint string.

pub fn subject(&self) -> &str

The subject alone, used to widen the reconciliation candidate window.

pub fn subject_predicate(&self) -> &str

The subject-and-predicate prefix, used to find contradiction candidates.

Trait Implementations

impl Clone for FactFingerprint

fn clone(&self) -> FactFingerprint

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for FactFingerprint

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for FactFingerprint

fn deserialize<__D>(__deserializer: __D) -> Result<Self, __D::Error>

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl Display for FactFingerprint

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

Formats the value using the given formatter.

impl Hash for FactFingerprint

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 FactFingerprint

fn cmp(&self, other: &FactFingerprint) -> 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 FactFingerprint

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

impl PartialOrd for FactFingerprint

fn partial_cmp(&self, other: &FactFingerprint) -> 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.

impl Serialize for FactFingerprint

fn serialize<__S>(&self, __serializer: __S) -> Result<__S::Ok, __S::Error>

where __S: Serializer,

Serialize this value into the given Serde serializer.
