Struct indradb::PipeVertexQuery

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

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<Type>

Filters the type of vertices returned.

Implementations

impl PipeVertexQuery

pub fn new(inner: Box<EdgeQuery>, direction: EdgeDirection, limit: u32) -> 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.
• limit - Limits the number of vertices to get.

pub fn t(self, t: Type) -> 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 From<PipeVertexQuery> for VertexQuery

fn from(query: PipeVertexQuery) -> Self

Converts to this type from the 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, limit: u32) -> PipeEdgeQuery

Gets the outbound edges associated with the vertices.

fn inbound(self, limit: u32) -> PipeEdgeQuery

Gets the inbound edges associated with the vertices.

fn property<S: Into<String>>(self, name: S) -> VertexPropertyQuery

Gets a property associated with the vertices.
