Struct neo4rs::Relation

pub struct Relation { /* private fields */ }

Snapshot of a relationship within a graph database

Implementations

impl Relation

pub fn new(inner: BoltRelation) -> Self

pub fn id(&self) -> i64

pub fn start_node_id(&self) -> i64

pub fn end_node_id(&self) -> i64

pub fn typ(&self) -> &str

pub fn keys(&self) -> Vec<&str>

Get the names of the attributes of this relationship

pub fn get<'this, T>(&'this self, key: &str) -> Result<T, DeError>

where T: Deserialize<'this>,

Get an attribute of this relationship and deserialize it into custom type that implements serde::Deserialize

pub fn to<'this, T>(&'this self) -> Result<T, DeError>

where T: Deserialize<'this>,

Deserialize the relationship into custom type that implements serde::Deserialize

Trait Implementations

impl Clone for Relation

fn clone(&self) -> Relation

Returns a copy of the value.

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

Performs copy-assignment from source.

impl Debug for Relation

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

Formats the value using the given formatter.

impl<'de> Deserialize<'de> for Relation

fn deserialize<D>(deserializer: D) -> Result<Self, D::Error>

where D: Deserializer<'de>,

Deserialize this value from the given Serde deserializer.

impl PartialEq for Relation

fn eq(&self, other: &Relation) -> 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 TryFrom<BoltType> for Relation

type Error = Error

The type returned in the event of a conversion error.

fn try_from(input: BoltType) -> Result<Relation>

Performs the conversion.
