Struct GoalFeedbackStream 

pub struct GoalFeedbackStream<'a, A, const GOAL_BUF: usize = nros_node::::executor::handles::GoalFeedbackStream::{constant#0}, const RESULT_BUF: usize = nros_node::::executor::handles::GoalFeedbackStream::{constant#1}, const FEEDBACK_BUF: usize = nros_node::::executor::handles::GoalFeedbackStream::{constant#2}>
where
    A: RosAction,
{ /* private fields */ }

A goal-filtered feedback stream.

Created by ActionClient::feedback_stream_for(). Only yields feedback messages matching the specified goal ID.

Implementations

impl<A, const GOAL_BUF: usize, const RESULT_BUF: usize, const FEEDBACK_BUF: usize> GoalFeedbackStream<'_, A, GOAL_BUF, RESULT_BUF, FEEDBACK_BUF>

where A: RosAction,

pub async fn recv( &mut self, ) -> Option<Result<<A as RosAction>::Feedback, NodeError>>

Async: wait for the next feedback message for this goal (no futures dependency needed).

When the stream feature is enabled, prefer StreamExt::next() or TryStreamExt::try_next() for combinator support.

pub fn wait_next( &mut self, executor: &mut Executor, timeout: Duration, ) -> Result<Option<<A as RosAction>::Feedback>, NodeError>

Sync: wait for the next feedback message for this goal, spinning the executor.
