Struct GraphConfigBuilder 

pub struct GraphConfigBuilder { /* private fields */ }

Builder for GraphConfig

Implementations

impl GraphConfigBuilder

pub fn new() -> Self

Create a new builder

pub fn node_table<S: Into<String>>(self, label: S, primary_key: S) -> Self

A node table: the nodes labelled label, one per row of the dataset of the same name, identified by its primary_key column.

Labels are case-insensitive: adding “Person” and then “person” keeps the second.

pub fn rel_table<S: Into<String>>( self, rel_type: S, from_table: S, to_table: S, src: S, dst: S, ) -> Self

A relationship table: edges of type rel_type from from_table nodes to to_table nodes, one per row of the dataset of the same name, with the source node’s key in column src and the target node’s key in column dst. Both node tables must be defined by the time Self::build runs.

pub fn with_node_label<S: Into<String>>(self, label: S, id_field: S) -> Self

👎Deprecated since 0.2.0:

use node_table

Add a node label mapping.

pub fn with_node_mapping(self, mapping: NodeMapping) -> Self

Add a node mapping with additional configuration

pub fn with_relationship<S: Into<String>>( self, rel_type: S, source_field: S, target_field: S, ) -> Self

👎Deprecated since 0.2.0:

use rel_table, which also takes the node tables at both ends

Add a relationship type mapping, without endpoint node tables.

pub fn with_relationship_endpoints<S: Into<String>>( self, rel_type: &str, source_label: S, target_label: S, ) -> Self

👎Deprecated since 0.2.0:

use rel_table, which takes the endpoint node tables

Record the node labels a configured relationship type connects (see RelationshipMapping::source_label). No-op for an unknown type.

pub fn with_relationship_mapping(self, mapping: RelationshipMapping) -> Self

Add a relationship mapping with additional configuration

pub fn with_default_node_id_field<S: Into<String>>(self, field: S) -> Self

Set the default node ID field

pub fn with_default_relationship_type_field<S: Into<String>>( self, field: S, ) -> Self

Set the default relationship type field

pub fn build(self) -> Result<GraphConfig>

Build the GraphConfig

Trait Implementations

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

Performs copy-assignment from source.

impl Debug for GraphConfigBuilder

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for GraphConfigBuilder

fn default() -> Self

Returns the “default value” for a type.
