Struct MatcherRef

pub struct MatcherRef<'a, T: ?Sized>(/* private fields */);

Result type of TermMatcher::matcher_ref and GraphNameMatcher::matcher_ref.

Trait Implementations

impl<'a, T> Clone for MatcherRef<'a, T>

fn clone(&self) -> Self

Returns a copy of the value.

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

Performs copy-assignment from source.

impl<'a, T: Debug + ?Sized> Debug for MatcherRef<'a, T>

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

Formats the value using the given formatter.

impl<'a, T: GraphNameMatcher + ?Sized> GraphNameMatcher for MatcherRef<'a, T>

type Term = <T as GraphNameMatcher>::Term

The type of term that this GraphNameMatcher contains

fn matches<T2: Term + ?Sized>(&self, graph_name: GraphName<&T2>) -> bool

Check whether this matcher matches t.

fn constant(&self) -> Option<GraphName<&Self::Term>>

Return None, unless this matcher can only match a single graph name, in which case this method may return that graph name.

fn matcher_ref(&self) -> MatcherRef<'_, Self>

Return a GraphNameMatcher that is actually just a reference to this one.

impl<'a, T: TermMatcher + ?Sized> TermMatcher for MatcherRef<'a, T>

type Term = <T as TermMatcher>::Term

The type of term that this TermMatcher contains

fn matches<T2: Term + ?Sized>(&self, term: &T2) -> bool

Check whether this matcher matches t.

fn constant(&self) -> Option<&Self::Term>

Return None, unless this matcher can only match a single term, in which case this method may return that term.

fn gn(self) -> TermMatcherGn<Self>

where Self: Sized,

Converts this TermMatcher into a GraphNameMatcher

fn matcher_ref(&self) -> MatcherRef<'_, Self>

Return a TermMatcher that is actually just a reference to this one.
