Struct indradb_proto::Transaction [−][src]
pub struct Transaction { /* fields omitted */ }Expand description
A transaction.
Implementations
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.
Arguments
vertex: The vertex to create.
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.
Arguments
t: The type of the vertex to create.

&mut self,
q: Q
) -> Result<Vec<Vertex>, ClientError>
pub async fn get_vertices<Q: Into<VertexQuery>>(
&mut self,
q: Q
) -> Result<Vec<Vertex>, ClientError>
pub async fn delete_vertices<Q: Into<VertexQuery>>(
&mut self,
q: Q
) -> Result<(), ClientError>
pub async fn delete_vertices<Q: Into<VertexQuery>>(
&mut self,
q: Q
) -> Result<(), ClientError>
Gets the number of vertices in the datastore.
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.
Arguments
key: The edge to create.
pub async fn get_edge_count(
&mut self,
id: Uuid,
t: Option<&Type>,
direction: EdgeDirection
) -> Result<u64, ClientError>
pub async fn get_edge_count(
&mut self,
id: Uuid,
t: Option<&Type>,
direction: EdgeDirection
) -> Result<u64, ClientError>
Gets the number of edges associated with a vertex.
Arguments
id: The id of the vertex.t: Only get the count for a specified edge type.direction: The direction of edges to get.
