Struct NodeDefaults 

pub struct NodeDefaults {
    pub retry: Option<RetryPolicy>,
    pub timeout: Option<TimeoutPolicy>,
    pub error_handler: Option<NodeErrorHandler>,
}

Policies a graph applies to every node that does not set its own.

Repeating the same retry or timeout on twenty nodes is easy to get wrong by omission. A default states it once; a per-node value always wins.

Example

use adk_graph::graph::NodeDefaults;
use adk_graph::retry::RetryPolicy;
use adk_graph::timeout::TimeoutPolicy;
use std::time::Duration;

let defaults = NodeDefaults::new().with_retry(RetryPolicy::new(3)).with_timeout(
    TimeoutPolicy { run_timeout: Some(Duration::from_secs(30)), ..Default::default() },
);

Fields

retry: Option<RetryPolicy>

Retry policy for a node with none of its own.

timeout: Option<TimeoutPolicy>

Timeout policy for a node with none of its own.

error_handler: Option<NodeErrorHandler>

Failure handler for a node with none of its own.

Implementations

impl NodeDefaults

pub fn new() -> Self

An empty set of defaults, which changes nothing.

pub fn with_retry(self, policy: RetryPolicy) -> Self

Applies this retry policy to every node that sets none.

pub fn with_timeout(self, policy: TimeoutPolicy) -> Self

Applies this timeout policy to every node that sets none.

pub fn with_error_handler<F>(self, handler: F) -> Self

where F: Fn(&str, &GraphError, &State) -> Result<NodeOutput> + Send + Sync + 'static,

Applies this failure handler to every node that sets none.

Trait Implementations

impl Clone for NodeDefaults

fn clone(&self) -> NodeDefaults

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl Debug for NodeDefaults

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

Formats the value using the given formatter.

impl Default for NodeDefaults

fn default() -> NodeDefaults

Returns the “default value” for a type.
