Struct indradb::PipeEdgeQuery

pub struct PipeEdgeQuery {
    pub inner: Box<VertexQuery>,
    pub direction: EdgeDirection,
    pub limit: u32,
    pub t: Option<Identifier>,
    pub high: Option<DateTime<Utc>>,
    pub low: Option<DateTime<Utc>>,
}

Gets the edges associated with vertices.

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

Fields

inner: Box<VertexQuery>

The vertex query to build off of.

direction: EdgeDirection

Whether to get outbound or inbound edges on the vertices.

limit: u32

Limits the number of edges to get.

t: Option<Identifier>

Filters the type of edges returned.

high: Option<DateTime<Utc>>

Specifies the newest update datetime for returned edges.

low: Option<DateTime<Utc>>

Specifies the oldest update datetime for returned edges.

Implementations

impl PipeEdgeQuery

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

Creates a new pipe edge query.

Arguments

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

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 edges returned.

Arguments

• t: Sets the type filter.

pub fn high(self, high: DateTime<Utc>) -> Self

Filter the update datetime of the edges returned.

Arguments

• high: The newest update datetime for the edges returned.

pub fn low(self, low: DateTime<Utc>) -> Self

Filter the update datetime of the edges returned.

Arguments

• low: The oldest update datetime for the edges returned.

Trait Implementations

impl Clone for PipeEdgeQuery

fn clone(&self) -> PipeEdgeQuery

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PipeEdgeQuery

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

Formats the value using the given formatter.

impl EdgeQueryExt for PipeEdgeQuery

fn outbound(self) -> PipeVertexQuery

Gets the vertices associated with the outbound end of the edges.

fn inbound(self) -> PipeVertexQuery

Gets the vertices associated with the inbound end of the edges.

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

Gets a property associated with the edges.

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

Gets edges with a property.

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

Gets edges without a property.

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

Gets edges with a property equal to a given value.

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

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

impl Into<EdgeQuery> for PipeEdgeQuery

fn into(self) -> EdgeQuery

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

impl PartialEq<PipeEdgeQuery> for PipeEdgeQuery

fn eq(&self, other: &PipeEdgeQuery) -> 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.
