Struct indradb::PipePropertyPresenceVertexQuery

pub struct PipePropertyPresenceVertexQuery {
    pub inner: Box<VertexQuery>,
    pub name: Identifier,
    pub exists: bool,
}

Gets vertices with a property.

Fields

inner: Box<VertexQuery>

The query to filter.

name: Identifier

The name of the property.

exists: bool

Whether we should look for property presence or lack thereof.

Implementations

impl PipePropertyPresenceVertexQuery

pub fn new<T: Into<Identifier>>(
    inner: Box<VertexQuery>,
    name: T,
    exists: bool
) -> Self

Gets vertices with a property.

Arguments

• inner: The query to filter.
• name: The name of the property.
• exists: Whether we should look for property presence or lack thereof.

Trait Implementations

impl Clone for PipePropertyPresenceVertexQuery

fn clone(&self) -> PipePropertyPresenceVertexQuery

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for PipePropertyPresenceVertexQuery

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

Formats the value using the given formatter.

impl Into<VertexQuery> for PipePropertyPresenceVertexQuery

fn into(self) -> VertexQuery

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

impl PartialEq<PipePropertyPresenceVertexQuery> for PipePropertyPresenceVertexQuery

fn eq(&self, other: &PipePropertyPresenceVertexQuery) -> 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 PipePropertyPresenceVertexQuery

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.
