Struct ExecutionConfig 

pub struct ExecutionConfig {
    pub thread_id: String,
    pub resume_from: Option<String>,
    pub recursion_limit: usize,
    pub metadata: HashMap<String, Value>,
    pub parent_context: Option<Arc<dyn InvocationContext>>,
}

Configuration passed to nodes during execution

Fields

thread_id: String

Thread identifier for checkpointing

resume_from: Option<String>

Resume from a specific checkpoint

recursion_limit: usize

Recursion limit for cycles

metadata: HashMap<String, Value>

Additional configuration

parent_context: Option<Arc<dyn InvocationContext>>

The invocation this graph run belongs to, when it has one.

An AgentNode runs a real agent, and that agent expects the identity, services, and cancellation of the run it belongs to. Without a parent the node has to fabricate them, which makes an agent behave differently inside a graph than outside it. Set this with ExecutionConfig::with_parent_context to carry them through; leaving it unset is standalone mode and is what a graph invoked outside a Runner gets.

Implementations

impl ExecutionConfig

pub fn new(thread_id: &str) -> Self

Create a new config with the given thread ID

pub fn with_parent_context(self, parent: Arc<dyn InvocationContext>) -> Self

Carry the invocation this graph run belongs to into its nodes.

An AgentNode then presents the caller’s identity, services, request context, and cancellation to the agent it runs, instead of a synthetic standalone context.

pub fn with_recursion_limit(self, limit: usize) -> Self

Set the recursion limit

pub fn with_resume_from(self, checkpoint_id: &str) -> Self

Resume from a specific checkpoint

pub fn with_metadata(self, key: &str, value: Value) -> Self

Add metadata

Trait Implementations

impl Clone for ExecutionConfig

fn clone(&self) -> ExecutionConfig

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Default for ExecutionConfig

fn default() -> Self

Returns the “default value” for a type.
