Struct TriplePattern 

pub struct TriplePattern {
    pub subject: Option<SubjectPattern>,
    pub predicate: Option<PredicatePattern>,
    pub object: Option<ObjectPattern>,
}

A pattern for matching triples

Fields

subject: Option<SubjectPattern>

predicate: Option<PredicatePattern>

object: Option<ObjectPattern>

Implementations

impl TriplePattern

pub fn new( subject: Option<SubjectPattern>, predicate: Option<PredicatePattern>, object: Option<ObjectPattern>, ) -> Self

Create a new triple pattern

pub fn subject(&self) -> Option<&SubjectPattern>

Get the subject pattern

pub fn predicate(&self) -> Option<&PredicatePattern>

Get the predicate pattern

pub fn object(&self) -> Option<&ObjectPattern>

Get the object pattern

pub fn matches(&self, triple: &Triple) -> bool

Check if a triple matches this pattern

Trait Implementations

impl Clone for TriplePattern

fn clone(&self) -> TriplePattern

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for TriplePattern

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for TriplePattern

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

where __D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl From<TriplePattern> for Option<AlgebraTriplePattern>

fn from(pattern: TriplePattern) -> Self

Converts to this type from the input type.

impl Hash for TriplePattern

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 TriplePattern

fn eq(&self, other: &TriplePattern) -> 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 Serialize for TriplePattern

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

where __S: Serializer,

Serialize this value into the given Serde serializer.

impl Eq for TriplePattern
