Struct ParallelNode 

pub struct ParallelNode { /* private fields */ }

Executes all child behaviors concurrently (in parallel).

Behavior:

• Ticks all children every tick
• Success/failure depends on the configured policy
• Returns Running while any child is still running

Use cases:

• Concurrent actions (move + look around + monitor obstacles)
• Parallel sensor processing
• Multi-objective optimization

Example

use mecha10_behavior_runtime::prelude::*;

// Assuming these behaviors are defined elsewhere
// All must succeed
let parallel = ParallelNode::new(
    get_behaviors(),
    ParallelPolicy::RequireAll,
);

Implementations

impl ParallelNode

pub fn new( children: Vec<Box<dyn BehaviorNode>>, policy: ParallelPolicy, ) -> ParallelNode

Create a new parallel node with the given children and policy.

pub fn add_child(&mut self, child: Box<dyn BehaviorNode>)

Add a child behavior to the parallel node.

pub fn len(&self) -> usize

Get the number of children.

pub fn is_empty(&self) -> bool

Check if the parallel node is empty.

Trait Implementations

impl BehaviorNode for ParallelNode

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, ParallelNode: 'async_trait,

Execute one tick of the behavior.

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

where 'life0: 'async_trait, ParallelNode: '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, ParallelNode: '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, ParallelNode: 'async_trait,

Called when the behavior is being terminated.

fn name(&self) -> &str

Get the name of this behavior node.

impl Debug for ParallelNode

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