Struct GraphBuilder 

pub struct GraphBuilder { /* private fields */ }

Implementations

impl GraphBuilder

pub fn new() -> Self

pub fn edge_policy(self, edge_policy: EdgePolicy) -> Self

pub fn node<'a>( &'a mut self, label: impl Into<Label>, id: impl Into<NodeId>, ) -> NodeBuilder<'a>

pub fn edge<'a>( &'a mut self, label: impl Into<Label>, from: impl Into<NodeId>, to: impl Into<NodeId>, ) -> EdgeBuilder<'a>

pub fn add_node(&mut self, node: Node) -> NodeId

Adds a node, merging with any existing node that has the same id.

If a node with the same id and the same label already exists, the new props are merged in (new values win). If a node with the same id but a different label exists, the new node replaces it entirely (last write wins, matching GraphStore::put_node overwrite semantics).

pub fn add_edge(&mut self, edge: Edge) -> PutOutcome

Adds an edge, reporting whether it was stored or dropped by the builder’s EdgePolicy.

pub fn build(self) -> Graph
