Struct Properties

pub struct Properties<P: PropertiesOps + Clone> { /* private fields */ }

View of the properties of an entity (graph|node|edge)

Implementations

impl<P: PropertiesOps + Clone> Properties<P>

pub fn new(props: P) -> Properties<P>

pub fn get(&self, key: &str) -> Option<Prop>

Get property value.

First searches temporal properties and returns latest value if it exists. If not, it falls back to static properties.

pub fn get_by_id(&self, id: usize) -> Option<Prop>

pub fn contains(&self, key: &str) -> bool

Check if property key exists.

pub fn keys(&self) -> impl Iterator<Item = ArcStr> + '_

Iterate over all property keys

pub fn values(&self) -> impl Iterator<Item = Prop> + '_

Iterate over all property values

pub fn iter(&self) -> impl Iterator<Item = (ArcStr, Prop)> + '_

Iterate over all property key-value pairs

pub fn temporal(&self) -> TemporalProperties<P>

Get a view of the temporal properties only.

pub fn constant<'a>(&self) -> ConstProperties<'a, P>

Get a view of the constant properties (meta-data) only.

pub fn as_vec(&self) -> Vec<(ArcStr, Prop)>

Collect properties into vector

pub fn as_map(&self) -> HashMap<ArcStr, Prop>

Collect properties into map

pub fn len(&self) -> usize

Number of properties

pub fn is_empty(&self) -> bool

Check if there are no properties

Trait Implementations

impl<P: Clone + PropertiesOps + Clone> Clone for Properties<P>
