Struct SequenceNode 

pub struct SequenceNode { /* private fields */ }

Executes child behaviors in sequence until one fails or all succeed.

Behavior:

• Ticks children in order
• Returns Success if all children succeed
• Returns Failure if any child fails
• Returns Running while executing children

Use cases:

• Multi-step tasks that must complete in order
• Pipeline processing
• Sequential actions (approach → grasp → lift)

Example

use mecha10_behavior_runtime::prelude::*;

// Assuming these behaviors are defined elsewhere
let sequence = SequenceNode::new(get_behaviors());

Implementations

impl SequenceNode

pub fn new(children: Vec<Box<dyn BehaviorNode>>) -> SequenceNode

Create a new sequence node with the given children.

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

Add a child behavior to the sequence.

pub fn len(&self) -> usize

Get the number of children.

pub fn is_empty(&self) -> bool

Check if the sequence is empty.

Trait Implementations

impl BehaviorNode for SequenceNode

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, SequenceNode: '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, SequenceNode: '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, SequenceNode: '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, SequenceNode: 'async_trait,

Called when the behavior is being terminated.

fn name(&self) -> &str

Get the name of this behavior node.

impl Debug for SequenceNode

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

Formats the value using the given formatter.
