Struct indradb::PipeVertexQuery

pub struct PipeVertexQuery {
    pub inner: Box<EdgeQuery>,
    pub direction: EdgeDirection,
    pub limit: u32,
    pub t: Option<Identifier>,
}

Gets the vertices associated with edges.

Generally, you shouldn’t need to construct this directly, but rather call .outbound() or .inbound() on an edge query.

Fields

inner: Box<EdgeQuery>

The edge query to build off of.

direction: EdgeDirection

Whether to get outbound or inbound vertices on the edges.

limit: u32

Limits the number of vertices to get.

t: Option<Identifier>

Filters the type of vertices returned.

Implementations

impl PipeVertexQuery

pub fn new(inner: Box<EdgeQuery>, direction: EdgeDirection) -> Self

Creates a new pipe vertex query.

Arguments

• inner: The edge query to build off of.
• direction: Whether to get outbound or inbound vertices on the edges.

pub fn limit(self, limit: u32) -> Self

Sets the limit.

Arguments

• limit: Limits the number of returned results.

pub fn t(self, t: Identifier) -> Self

Filter the type of vertices returned.

Arguments

• t: Sets the type filter.

Trait Implementations

impl Clone for PipeVertexQuery

fn clone(&self) -> PipeVertexQuery

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PipeVertexQuery

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

Formats the value using the given formatter.

impl Into<VertexQuery> for PipeVertexQuery

fn into(self) -> VertexQuery

Converts this type into the (usually inferred) input type.

impl PartialEq<PipeVertexQuery> for PipeVertexQuery

fn eq(&self, other: &PipeVertexQuery) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.

impl VertexQueryExt for PipeVertexQuery

fn outbound(self) -> PipeEdgeQuery

Gets the outbound edges associated with the vertices.

fn inbound(self) -> PipeEdgeQuery

Gets the inbound edges associated with the vertices.

fn property<T: Into<Identifier>>(self, name: T) -> VertexPropertyQuery

Gets a property associated with the vertices.

fn with_property<T: Into<Identifier>>(
    self,
    name: T
) -> PipePropertyPresenceVertexQuery

Gets vertices with a property.

fn without_property<T: Into<Identifier>>(
    self,
    name: T
) -> PipePropertyPresenceVertexQuery

Gets vertices without a property.

fn with_property_equal_to<T: Into<Identifier>>(
    self,
    name: T,
    value: Value
) -> PipePropertyValueVertexQuery

Gets vertices with a property equal to a given value.

fn with_property_not_equal_to<T: Into<Identifier>>(
    self,
    name: T,
    value: Value
) -> PipePropertyValueVertexQuery

Gets vertices with a property not equal to a given value.
