Struct RetryNode 

pub struct RetryNode { /* private fields */ }

Re-runs its child up to max_attempts times whenever it fails, succeeding as soon as one attempt succeeds; only reports Failure once every attempt has been exhausted. The complement of RepeatNode (which loops on success) - for flaky/best-effort actions like a detection scan that may need a few tries (e.g. capture-target’s “take a picture of a uniquely-found target”).

Implementations

impl RetryNode

pub fn new(child: Box<dyn BehaviorNode>, max_attempts: u32) -> RetryNode

Create a new retry node wrapping child, allowing up to max_attempts tries (must be at least 1).

Trait Implementations

impl BehaviorNode for RetryNode

fn tick<'life0, 'life1, 'async_trait>( &'life0 mut self, ctx: &'life1 Context, ) -> Pin<Box<dyn Future<Output = Result<NodeStatus, Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, RetryNode: 'async_trait,

Execute one tick of the behavior.

fn reset_self(&mut self)

Reset this node’s own local state, ignoring children.

fn name(&self) -> &str

Get the name of this behavior node.

fn children_mut(&mut self) -> Vec<&mut dyn BehaviorNode>

Return mutable references to this node’s child behaviors, in the order they should receive lifecycle events.

fn active_capability(&self) -> Option<&str>

The capability this node implies should be published on /behavior/status while it’s the one actively being ticked (e.g. rl_task’s hardcoded "rl", gating RlNode::is_active() on the rl node crate’s side) - None for a node with no such gate (the default, correct for the vast majority of leaves and for a composite with no currently-active child).

fn reset<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, Self: 'async_trait,

Reset the behavior to its initial state.

fn on_init<'life0, 'life1, 'async_trait>( &'life0 mut self, ctx: &'life1 Context, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Called when the behavior is first initialized.

fn on_terminate<'life0, 'life1, 'async_trait>( &'life0 mut self, ctx: &'life1 Context, ) -> Pin<Box<dyn Future<Output = Result<(), Error>> + Send + 'async_trait>>

where 'life0: 'async_trait, 'life1: 'async_trait, Self: 'async_trait,

Called when the behavior is being terminated.

impl Debug for RetryNode

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

Formats the value using the given formatter.
