Implementations

impl<'a> PropertyRepository<'a>

pub fn new(ds_ref: DatastoreRef<'a>) -> Self

pub fn tx(&self) -> Transaction

pub fn mut_tx(&self) -> Transaction

pub async fn count(&self) -> Result<usize, Error>

impl<'a> PropertyRepository<'a>

pub async fn property(
    &self,
    tx: &mut Transaction,
    vertex_id: &GID,
    label: &GValue,
    value: &GValue
) -> Result<Property, Error>

The property()-step is used to add properties to the elements of the graph (sideEffect). Unlike addV() and addE(), property() is a full sideEffect step in that it does not return the property it created, but the element that streamed into it. Moreover, if property() follows an addV() or addE(), then it is “folded” into the previous step to enable vertex and edge creation with all its properties in one creation operation.

pub async fn iterate_from_vertex(
    &self,
    tx: &Transaction,
    vertex_id: &GID
) -> Result<HashMap<String, Property>, Error>

Method to iterate the pairs of byte data with prefix as vertex id

Trait Implementations

impl<'a> Clone for PropertyRepository<'a>

fn clone(&self) -> PropertyRepository<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.
