Enum Query 

pub enum Query<Id: IdType> {
    NodeProps(HashSet<Id>),
    SPO(HashSet<(Id, Id, Id)>),
    O(HashSet<Id>),
    S(HashSet<Id>),
    P(HashSet<Id>),
    PO(HashSet<(Id, Id)>),
    SO(HashSet<(Id, Id)>),
    SP(HashSet<(Id, Id)>),
}

Represents a query which can be executed on a [TripleStore][crate::TripleStore].

These are most easily created using teh query macro.

Variants

NodeProps(HashSet<Id>)

Fetch the NodeProps for the given set of ids.

SPO(HashSet<(Id, Id, Id)>)

Fetch the edges for the given set of triples.

O(HashSet<Id>)

Fetch all edges which point to one of the given set of ids.

S(HashSet<Id>)

Fetch all edges which start at one of the given set of ids.

P(HashSet<Id>)

Fetch all edges which have one of the given set of edge ids.

PO(HashSet<(Id, Id)>)

Fetch all edges which have one of the given tuples as predicate and object.

SO(HashSet<(Id, Id)>)

Fetch all edges which have one of the given tuples as subject and object.

SP(HashSet<(Id, Id)>)

Fetch all edges which have one of the given tuples as subject and predicate.

Trait Implementations

impl<Id: Clone + IdType> Clone for Query<Id>

fn clone(&self) -> Query<Id>

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<Id: Debug + IdType> Debug for Query<Id>

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

Formats the value using the given formatter.

impl<Id: IdType, I: IntoIterator<Item = Triple<Id>>> From<I> for Query<Id>

fn from(value: I) -> Self

Converts to this type from the input type.

impl<Id: PartialEq + IdType> PartialEq for Query<Id>

fn eq(&self, other: &Query<Id>) -> 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.
