Struct PipeQuery

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

Gets the vertices associated with edges, or edges associated with vertices.

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

Fields

inner: Box<Query>

The edge query to build off of.

direction: EdgeDirection

Whether to get outbound or inbound values.

limit: u32

Limits the number of values to get.

t: Option<Identifier>

Filters the type of values returned.

Implementations

impl PipeQuery

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

Constructs a new pipe query.

Arguments

• inner: The inner query.
• direction: Which direction to pipe from.

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 values returned.

Arguments

• t: Sets the type filter.

Trait Implementations

impl Clone for PipeQuery

fn clone(&self) -> PipeQuery

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl CountQueryExt for PipeQuery

fn count(self) -> ValidationResult<CountQuery>

Gets the count from this query.

impl Debug for PipeQuery

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

Formats the value using the given formatter.

impl Into<Query> for PipeQuery

fn into(self) -> Query

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

impl PartialEq for PipeQuery

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

impl QueryExt for PipeQuery

fn outbound(self) -> ValidationResult<PipeQuery>

Gets the outbound vertices or edges associated with this query.

fn inbound(self) -> ValidationResult<PipeQuery>

Gets the inbound vertices or edges associated with this query.

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

Gets values with a property.

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

Gets values without a property.

fn with_property_equal_to<T: Into<Identifier>>( self, name: T, value: Json, ) -> ValidationResult<PipeWithPropertyValueQuery>

Gets values with a property equal to a given value.

fn with_property_not_equal_to<T: Into<Identifier>>( self, name: T, value: Json, ) -> ValidationResult<PipeWithPropertyValueQuery>

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

fn properties(self) -> ValidationResult<PipePropertyQuery>

Gets the properties associated with the query results.

fn include(self) -> IncludeQuery

Include this query’s output, even if it is an intermediate result.
