Struct VertexProperty 

pub struct VertexProperty { /* private fields */ }

VertexProperty

Description

A VertexProperty is similar to a Property in that it denotes a key/value pair associated with an Vertex, however it is different in the sense that it also represents an entity that it is an Element that can have properties of its own.

TinkerPop Documentation

TinkerPop introduces the concept of a VertexProperty. All the properties of a Vertex are a VertexProperty. A VertexProperty implements Property and as such, it has a key/value pair. However, VertexProperty also implements Element and thus, can have a collection of key/value pairs. Moreover, while an Edge can only have one property of key “name” (for example), a Vertex can have multiple “name” properties. With the inclusion of vertex properties, two features are introduced which ultimately advance the graph modelers toolkit:

Implementations

impl VertexProperty

pub fn new<G, T, GT>(id: G, label: T, value: GT) -> VertexProperty

where G: Into<GID>, T: Into<String>, GT: Into<GValue>,

pub fn id(&self) -> &GID

pub fn value(&self) -> &GValue

pub fn take<T>(self) -> GremlinResult<T>

where T: FromGValue,

pub fn get<'a, T>(&'a self) -> GremlinResult<&'a T>

where T: BorrowFromGValue,

pub fn label(&self) -> &String

Trait Implementations

impl Clone for VertexProperty

fn clone(&self) -> VertexProperty

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for VertexProperty

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

Formats the value using the given formatter.

impl From<VertexProperty> for GValue

fn from(val: VertexProperty) -> Self

Converts to this type from the input type.

impl PartialEq for VertexProperty

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