Implementations

impl<T> AnySubject<T>

pub fn from_option_quad( p: Option<T>, o: Option<T>, g: Option<Option<T>>, ) -> Self

Builds a pattern from a quad whose unset positions match anything.

pub fn from_pattern<X: PartialEq>( s: X, p: ResourceOrVar<T, X>, o: ResourceOrVar<T, X>, g: Option<ResourceOrVar<T, X>>, ) -> Self

Builds a pattern from pattern, canonicalizing repeated variables into SameAs positions.

pub const fn predicate(&self) -> PatternPredicate<&T>

Returns the predicate of this pattern.

pub fn into_predicate(self) -> PatternPredicate<T>

Consumes this pattern, returning its predicate.

pub const fn object(&self) -> PatternObject<&T>

Returns the object of this pattern.

pub fn into_object(self) -> PatternObject<T>

Consumes this pattern, returning its object.

pub const fn graph(&self) -> PatternGraph<&T>

Returns the graph of this pattern.

pub fn into_graph(self) -> PatternGraph<T>

Consumes this pattern, returning its graph.

pub const fn as_ref(&self) -> AnySubject<&T>

Borrows the resources of this pattern.

pub fn map<U>(self, f: impl FnMut(T) -> U) -> AnySubject<U>

Maps the resources of this pattern with f.

pub fn map2<U, V>( self, f: impl FnMut(T) -> (U, V), ) -> (AnySubject<U>, AnySubject<V>)

Maps each resource to a pair with f, splitting this pattern in two.

pub fn into_triple(self) -> (AnySubject<T>, PatternGraph<T>)

Splits this quad pattern into a triple pattern and a graph pattern.

pub fn into_parts( self, ) -> (PatternPredicate<T>, PatternObject<T>, PatternGraph<T>)

Consumes this pattern, returning each position separately.
