Struct StateGraph 

pub struct StateGraph<S: State> { /* private fields */ }

Builder for constructing a state graph.

Implementations

impl<S: State> StateGraph<S>

pub fn new() -> Self

pub fn add_node( self, name: impl Into<String>, node: impl Node<S> + 'static, ) -> Self

Add a named node to the graph.

pub fn add_edge( self, source: impl Into<String>, target: impl Into<String>, ) -> Self

Add a fixed edge from source to target.

pub fn add_conditional_edges( self, source: impl Into<String>, router: impl Fn(&S) -> String + Send + Sync + 'static, ) -> Self

Add a conditional edge with a routing function.

pub fn add_conditional_edges_with_path_map( self, source: impl Into<String>, router: impl Fn(&S) -> String + Send + Sync + 'static, path_map: HashMap<String, String>, ) -> Self

Add a conditional edge with a routing function and a path map for visualization.

The path_map maps labels to target node names, enabling graph visualization tools to show possible routing targets for conditional edges.

pub fn set_entry_point(self, name: impl Into<String>) -> Self

Set the entry point node for graph execution.

pub fn interrupt_before(self, nodes: Vec<String>) -> Self

Mark nodes that should interrupt BEFORE execution (human-in-the-loop).

pub fn interrupt_after(self, nodes: Vec<String>) -> Self

Mark nodes that should interrupt AFTER execution (human-in-the-loop).

pub fn compile(self) -> Result<CompiledGraph<S>, SynapseError>

Compile the graph into an executable CompiledGraph.

Trait Implementations

impl<S: State> Default for StateGraph<S>

fn default() -> Self

Returns the “default value” for a type.
