Trait Implementations

impl Debug for ProxyTransaction

fn fmt(&self, __arg_0: &mut Formatter) -> Result

Formats the value using the given formatter.

impl Transaction for ProxyTransaction

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

Gets a range of vertices specified by a query.

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

Creates a new vertex.

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, key: &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_global_metadata(&self, key: &str) -> Result<Option<JsonValue>, Error>

Gets a global metadata value.

fn set_global_metadata(&self, key: &str, value: &JsonValue) -> Result<(), Error>

Sets a global metadata value.

fn delete_global_metadata(&self, key: &str) -> Result<(), Error>

Deletes a global metadata value.

fn get_vertex_metadata(
    &self,
    q: &VertexQuery,
    key: &str
) -> Result<Vec<VertexMetadata>, Error>

Gets a vertex metadata value.

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

Sets a vertex metadata value.

fn delete_vertex_metadata(
    &self,
    q: &VertexQuery,
    key: &str
) -> Result<(), Error>

Deletes a vertex metadata value.

fn get_edge_metadata(
    &self,
    q: &EdgeQuery,
    key: &str
) -> Result<Vec<EdgeMetadata>, Error>

Gets an edge metadata value.

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

Sets an edge metadata value.

fn delete_edge_metadata(&self, q: &EdgeQuery, key: &str) -> Result<(), Error>

Deletes an edge metadata value.
