Trait Implementations

impl Transaction for ClientTransaction

fn create_vertex(&self, v: &Vertex) -> Result<bool, Error>

Creates a new vertex. Returns whether the vertex was successfully created - if this is false, it’s because a vertex with the same UUID already exists.

fn create_vertex_from_type(&self, t: Type) -> Result<Uuid, Error>

Creates a new vertex with just a type specification. As opposed to create_vertex, this is used when you do not want to manually specify the vertex’s UUID. Returns the new vertex’s UUID.

fn get_vertices(&self, q: &VertexQuery) -> Result<Vec<Vertex>, Error>

Gets a range of vertices specified by a query.

fn delete_vertices(&self, q: &VertexQuery) -> Result<(), Error>

Deletes existing vertices specified by a query.

fn get_vertex_count(&self) -> Result<u64, Error>

Gets the number of vertices in the datastore..

fn create_edge(&self, e: &EdgeKey) -> Result<bool, Error>

Creates a new edge. If the edge already exists, this will update it with a new update datetime. Returns whether the edge was successfully created - if this is false, it’s because one of the specified vertices is missing.

fn get_edges(&self, q: &EdgeQuery) -> Result<Vec<Edge>, Error>

Gets a range of edges specified by a query.

fn delete_edges(&self, q: &EdgeQuery) -> Result<(), Error>

Deletes a set of edges specified by a query.

fn get_edge_count(
    &self,
    id: Uuid,
    type_filter: Option<&Type>,
    direction: EdgeDirection
) -> Result<u64, Error>

Gets the number of edges associated with a vertex.

fn get_vertex_properties(
    &self,
    q: &VertexQuery,
    name: &str
) -> Result<Vec<VertexProperty>, Error>

Gets vertex properties.

fn set_vertex_properties(
    &self,
    q: &VertexQuery,
    name: &str,
    value: &JsonValue
) -> Result<(), Error>

Sets a vertex properties.

fn delete_vertex_properties(
    &self,
    q: &VertexQuery,
    name: &str
) -> Result<(), Error>

Deletes vertex properties.

fn get_edge_properties(
    &self,
    q: &EdgeQuery,
    name: &str
) -> Result<Vec<EdgeProperty>, Error>

Gets edge properties.

fn set_edge_properties(
    &self,
    q: &EdgeQuery,
    name: &str,
    value: &JsonValue
) -> Result<(), Error>

Sets edge properties.

fn delete_edge_properties(&self, q: &EdgeQuery, name: &str) -> Result<(), Error>

Deletes edge properties.
