Struct SelectOrNode 

pub struct SelectOrNode { /* private fields */ }

Executes child behaviors until one succeeds or all fail.

Behavior:

• Ticks children in order
• Returns Success if any child succeeds
• Returns Failure if all children fail
• Returns Running while executing children

Use cases:

• Fallback behaviors (try A, if it fails try B)
• Alternative strategies
• Error recovery chains

Example

use mecha10_behavior_runtime::prelude::*;

// Assuming these behaviors are defined elsewhere
let selector = SelectOrNode::new(get_behaviors());

Implementations

impl SelectOrNode

pub fn new(children: Vec<BoxedBehavior>) -> Self

Create a new selector node with the given children.

pub fn add_child(&mut self, child: BoxedBehavior)

Add a child behavior to the selector.

pub fn len(&self) -> usize

Get the number of children.

pub fn is_empty(&self) -> bool

Check if the selector is empty.

Trait Implementations

impl BehaviorNode for SelectOrNode

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

where Self: 'async_trait, 'life0: 'async_trait, 'life1: '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 reset<'life0, 'async_trait>( &'life0 mut self, ) -> Pin<Box<dyn Future<Output = Result<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: '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<()>> + Send + 'async_trait>>

where Self: 'async_trait, 'life0: 'async_trait, 'life1: '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<()>> + Send + 'async_trait>>

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

Called when the behavior is being terminated.

impl Debug for SelectOrNode

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

Formats the value using the given formatter.
