Struct DeferredNodeConfig 

pub struct DeferredNodeConfig {
    pub merge_strategy: MergeStrategy,
    pub fan_in_timeout: Option<Duration>,
    pub min_predecessors: Option<usize>,
}

Available on crate feature graph only.

Configuration for a deferred (fan-in) node.

A deferred node waits for all upstream parallel paths to complete before executing. The configuration controls how outputs are merged and how long the node waits.

Example

use std::time::Duration;
use adk_graph::deferred::{DeferredNodeConfig, MergeStrategy};

let config = DeferredNodeConfig {
    merge_strategy: MergeStrategy::MergeMap,
    fan_in_timeout: Some(Duration::from_secs(60)),
    ..Default::default()
};

Fields

merge_strategy: MergeStrategy

Strategy for combining upstream outputs.

fan_in_timeout: Option<Duration>

Maximum time to wait for all upstream paths to complete.

• None: Wait indefinitely for all upstream paths.
• Some(duration): If the timeout expires and some paths have completed, proceed with partial results. If zero paths have completed, return GraphError::FanInTimedOut.

min_predecessors: Option<usize>

How many predecessors must have arrived for fan_in_timeout to release the node with partial results.

None means one, which is the behaviour this field replaced. Set it to the full predecessor count to require all of them even after a timeout, or to any value between for an n-of-m join: release once that many branches have answered and abandon the rest.
