Struct indradb::RangeVertexQuery

pub struct RangeVertexQuery {
    pub limit: u32,
    pub t: Option<Identifier>,
    pub start_id: Option<Uuid>,
}

Gets a range of vertices.

Fields

limit: u32

Limits the number of vertices to get.

t: Option<Identifier>

Filters the type of vertices returned.

start_id: Option<Uuid>

Sets the lowest vertex ID to return.

Implementations

impl RangeVertexQuery

pub fn new() -> Self

Creates a new vertex range query.

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.

pub fn start_id(self, start_id: Uuid) -> Self

Sets the lowest vertex ID to return.

Arguments

• start_id: The lowest vertex ID to return.

Trait Implementations

impl Clone for RangeVertexQuery

fn clone(&self) -> RangeVertexQuery

Returns a copy of the value.

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

Performs copy-assignment from source.

impl CountQueryExt for RangeVertexQuery

fn count(self) -> ValidationResult<CountQuery>

Gets the count from this query.

impl Debug for RangeVertexQuery

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

Formats the value using the given formatter.

impl Default for RangeVertexQuery

fn default() -> Self

Returns the “default value” for a type.

impl Into<Query> for RangeVertexQuery

fn into(self) -> Query

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

impl PartialEq<RangeVertexQuery> for RangeVertexQuery

fn eq(&self, other: &RangeVertexQuery) -> 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 QueryExt for RangeVertexQuery

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.
